🎓 Reddit experts on file folders
The comments and opinions expressed on this page are written exclusively by redditors. To provide you with the most relevant data, we sourced opinions from the most knowledgeable Reddit users based the total number of upvotes and downvotes received across comments on subreddits where file folders are discussed. For your reference and for the sake of transparency, here are the specialists whose opinions mattered the most in our ranking.
Ok so I've never been on legaladviceuk before and I am by no means an expert but I don't know how long it takes for people to get good advice or if everyone does so here's my advice of steps you can take right away while you get better advice.
So my first piece of advice is don't panic. This man might be crazy but there are lots of things a landlord can't do and evict you just because he feels like it is one of them. You have lots of rights as a tenant and he can't force you to leave the property without a court order. Any attempts he makes to do so without one are very much in the domain of illegal. So don't let him get to you or your family. Chillax. Have a cup of tea and smugly sit on your sofa knowing he needs a judge to agree you're going before he kicks you out and that takes months.
You do not have to leave in two weeks if you don't want to. So do not panic.
And you are not going anywhere just because your Mum said she'd move out in a heated argument. That doesn't mean squat.
So you're just going to want to get a note pad that you can use as a diary and you're going to want to make the first entry the date of you calling the CO number and then coming over. The second entry about your interaction with your landlord and a summary of what he said while it's still fresh in your mind. Doesn't have to be anything complicated just a date and maybe a time and a brief description.
So it sounds like you've got a recording of him being crazy which is great because you're going to want to record everything and keep copies of everything. You're going to want a few plastic folders the ones with the button fronts that look like this.
Then you're going to want to get all the stuff you have to do with you renting which I don't know what you might have but a tenancy agreement, just any letters to do with you renting and put them in one of the folders. You can organize them later but just good to have them in one place. Then you're going to want one folder for any new stuff but we'll get to that but just have an empty folder you can keep stuff in.
For your photo evidence and this recording it would be a good idea to back it up to your computer if you have one or make a free google account and then put copies of them on there. Just so there somewhere easy to get to. Even just sending the photos over facebook messenger so that they're backed up there could be a good idea.
So yeah you're going to want to get more advice but until then just record everything. Type up a letter just saying in plain English how you'd like to deal with the problem with the gas and the threat of eviction in writing and not over the phone. How not to call your Mum but to write. Put the date on the top, then to: your landlords full name and address, then from: your name and address. Make TWO copies of it and put them in your folder. Don't give it to your landlord unless he gets in contact with you first by coming round the house or calling. If he calls say you would like to deal with this matter in writing and you'll be sending him a letter. Then buy an envelope stick one of them letters in it and put it in the post. Write copy at the bottom the other letter. If he calls or comes round the house make a note of it in your diary. If he comes round the house give him the letter in person and ask him to leave.
So now on to getting more advice. https://england.shelter.org.uk/ has loads of good advice and a free helpline. They will hopefully be able to tell you what to do and sign post you for resources in your area.
You can also go to your local citizens advice to get signposted to resources https://www.citizensadvice.org.uk/about-us/how-we-provide-advice/advice/search-for-your-local-citizens-advice/
There are lots of people out there who want to help people in the exact situation your in. So don't panic. You also likely qualify for legal aid.
Obviously you'll want to get your gas on as soon as possible which your landlord definitely has a duty to do and then you can decide what you want to do in terms of your living arrangements on your terms in your own time. Not because this man bullies you.
Also you really did a great job of explaining what's going on in this post so why not print this out so that if you go to a meeting with anyone you can use it as a guide to make sure you say everything you want or have them read it.
Good luck getting things sorted! Sorry your gas got turned off! Don't let this horrible man bully you! And make your Mum and cup of tea and reassure her you're gonna get help to sort this stuff out :)
For what it's worth, I think the LT1917 has become a standard because the original Bullet Journal web page sells them under their brand.
As mentioned here, LT1917 is 80gsm, which is relatively thin and makes a lot of pens bleed through and ghost. For more information about bleeding, ghosting, and general comparison between notebooks I recommend watching Which Notebook is the Best for Bullet Journaling?! (skip to 11:00 to see the comparison chart). I prefer Scribbles That Matter which is thicker (100gsm) and feels smoother to write on. My next purchase will probably be a Midori with 120gsm or a Rhodia to try them out.
One of the core principals of Bullet Journalism is that there are no hard rules. While it comes with some guidelines, you are free to use it however you see fit. Which means that there are no predefined pages. So for the most part you are going to be drawing the layouts. And this is why a Dotted paper helps because you can use the dots to draw your own layouts. You can checkout Pinterest for inspiration. The community uses the term "spreads" to signify two-page layouts used for all sorts of things.
As for pens, many recommend the Sakura Pigma Micron for good reason. While I use them for more "serious" work, when it comes to EDC I would highly recommend the Muji 0.38mm Fine Point Gel Pens. Unlike the Microns, they are not felt tip (which is why I wouldn't use them for EDC) but very sharp ball point pen with great consistency. A lot of people swear by the Pilot G2 0.38mm Ultra Fine Point but personally I wasn't pleased with them.
Finally, regarding the things you want to track, as I mentioned earlier, you can simply define the layouts of each page and track whatever you wish. A lot of the spreads you see from the community are really intricate. You can find a variety of them from very crazy daily layouts to minimal ones. It's all up to you.
Having said that, if drawing your own layouts daily seems like a lot of work (a lot of people actually spend a few hours planning them beforehand), then you might want to consider a more traditional Planner instead. As mentioned ITT, the Nomadic Planner has good paper (125gsm), weekly and monthly pages as well as lined and blanks for notes and the rest.
There is a whole universe of things to consider (and I'm more than happy to geek out about it), but I'd say just start with whatever. Don't think about it too much. Most of the negatives are personal, so while LT1917 doesn't work for some, it might for you. You'll figure things out as you go.
"Pimp my cube, /u/quinnundine!" "OKAY /u/kickballa!"
Congratulations! I teach middle-school ELA, and here are some of my systems:
Whew! I think that's enough for today. I hope you find something useful in that verbal dump. ;) If there's anything you want clarification on, just let me know!
NO lamination.
Gaylord Archival supply sells on Amazon and are a good company. Hit up your family for gift cards to Amazon to help defray costs as this stuff is expensive.
Paper can be stored in archival folders (they look like manilla or white ones but are acid-free) or poly folders. (FYI, I blow through tons of these from B&H, they seem more affordable than the gaylord ones.)
Put anything fragile in the poly sleeves, as close to the size as you can. (Or, in other words, don't let it bounce around in a sleeve that it too big, nor be damaged by one that is too small).
ONLY buy poly folders that are PAT" passed. It will be in the description or a little logo and is the only certification that matters. You will see all kinds of "archival-friendly" terms which are meaningless.
I put my tintypes in a photo sleeve and then into a box. Between each, I put a piece of felt (craft store) or heavy acid-free paper so they don't scratch each other.
Newspaper is the most frustrating as no matter what you do, it will continue to yellow and become brittle. The acids in the paper destroy it form within and only de-acidifying will slow it. But this is expensive and may destroy the piece. Make newspaper your scanning priority.
If you protect the individual items you can skip, for now, the super-expensive archival boxes and use regular boxes. As long as the items are safe, in a climate controlled environment, have pretty even temperature year-round, and no smoke, regular boxes are fine. Invest in protecting each item first—that will give you more bang for your buck.
BTW, a flatbed scanner works GREAT for scanning tintypes. Just invest in a stand-alone scanner with the highest resolution you can find. The kind attached to a printer is not made for photos and not worth scanning with. I like this model as it scans slides and negatives, too.
Scan documents at minimum of 300ppi (archives scan at 600ppi) and photos at minimum of 600ppi. The smaller the image the higher resolution you should scan. Save images as TIF or PNG, not JPG.
Also buy some back-up drives and/or a cloud subscription. You will chew up hard drive space but hard drives are cheap. Backups and cloud storage insures that you are protected in case your hard drive dies (which they do) or your house burns down.
Lastly, you can buy cotton gloves but many archives now prefer clean hands to gloves. When wearing gloves, it is almost impossible to feel what you are grabbing, and very easy to damage paper. Wash your hands well before handling materials and you should be fine.

UPDATE: Had wrong B&H link. Fixed.
This Rilakkuma folder is adorable AND useful!
And my favorite dinosaur is and will always be the ankylosaurus.
Thanks for the fun contest!
These are the folders I used: 4-section manila folder (Sections are the number of surfaces that papers can be fastened to. 4 section has one divider, for a total of 4 interior surfaces.)
(and these are a more simple folder I use for a different game: 2 section manila folders )
For the redacted documents, I used a chapter from one of david weber's honor harrington books (from the baen free library). The redacting itself took some time, but once done I just reprinted it for the other folders.
The largest component was time... actually making the characters was pretty fast. Since they were legendary rank, I just gave them what I wanted. :)
I'm thinking of upgrading to these 4-section or even these 6-section. They're pretty expensive, but they'll last a loooong time.
That's a gorgeous pen and I can vouch for the quality of Lamy pens, as well. I'm a fan of the 0.38mm MUJI pen, myself. 10-pack for ~$15 and they write wonderfully. Just as good as the 0.38mm Pilot G-2 pens I used to use.
I’ve taped together a series of heavyweight file folders for 7-8’ projects and been able to use them 8-10 times successfully.
I’ve gotten minimal overspray on smoother concrete using this repositionable adhesive spray but if it’s a rougher texture, the lines won’t be nearly as crisp. Still better than without using the adhesive, though.
Hope that’s helpful!
http://www.amazon.com/Days-Week-Folder-Knock/dp/1601064497 I ordered Her these for organizing her work in her bag, she is a bit OCD haha.
And she loves Cats so I ordered This to mark her books
I am loving the other ideas like clip board and binder clips.
I use clear plastic sleeves (something like this) for that exact purpose. It doesn't add any bulk and easily slips inside my backpack or in a notebook, and easy to carry by itself (I often clip a pen on it too) while keeping papers neat.
Congrats on your own office!!
Here is my list of office essentials:
Oh, and I think the only things under $5ish are on my mp3 WL. :)
As my group's current DM, I'm a little too excited for the chance to be a PC when someone in my group starts up CoS and rotating with my campaign. Everything I need in one spot, ready for session 0. A small part of me hopes he dies so I can buy a [DECEASED] stamp before he gets filed.
I use Muji .38 and I've been happy with them. If you can get them at an actual Muji store it's better; the Amazon markup is sort of absurd.
Here's mine.
I got a set of plastic document folders like these on Amazon. 3-hole punched the manuals, and those are secured with the brass tabs. Loose paper in the front cover's pocket. Made some self-adhesive labels with the game's logo for the front of each folder. Cheap, basically indestructible, and all my experts can pick their favorite color. Somebody absconded with the blue one so they could study up.
Here's some things outside of the obvious JJDIDTIEBUCKLE stuff that will make your life a little easier.
I use outlook to keep appointments together, but for notes I have a pretty odd system that does work for me. Fair warning, I'm hyper-organized about this type of thing. I'm a big tech nerd but I just can't stay organized keeping meeting notes electronically.
For every sit down meeting I use a piece of card stock. Weird I know, but the tangibility of it helps me. I make sure to put the date/customer on the top and at the next meeting with the same customer I flip it over to use again or start another. When I get back to my office I stick it in one of these closed file folders labeled with the customer name. I grab the folder when I go to the customer in case I need to look back on my notes, I prefer the closed sides so the cardstock sheets don't fall out.
I'd take a chance on some muji gel pens
https://www.amazon.com/gp/product/B00E391XXM/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
^ these are great
Thanks - I make a lot of notes as I dial a print in, and I might use 2 or 3 masking steps. So when I have a complex print, that neg ends up in its own folder, and the neg and masks go into glassine envelopes vs. a folder with the whole roll in a print file sleeve. I just put everything in a manila job jacket which is like a file folder but the sides are closed. I staple a 4x5 test print to the front and keep all the folders in a plastic file box. There's a zillion ways to keep track of stuff I'm sure, this works for me and allows me to re-print a neg months later and not have to start from scratch.
Just plastic Mead folders, with 3 braid binders. Here's an amazon link: http://www.amazon.com/Five-Star-Stay-Put-Pocket-72113/dp/B003O3IUT8
I prefer hard-backed 3 ring binders, but the player that did the folders used these. I think it's because they have the pocket and because it's easier to punch the holes in the front for the rivets.
You can get a 10 pack of them on Amazon: https://smile.amazon.com/Moma-Muji-Point-0-38-mm-Black/dp/B00E391XXM/ They're my favorite pens right now!
Surprised no one has mentioned Muji . They hit every requirement you ask for. My 0.38mm are great.
https://www.amazon.com/Moma-Muji-Point-0-38-mm-Black/dp/B00E391XXM
Are you talking about these? If so, I'm going to get them to try.
Qualcuno sa come si chiamano queste in italiano? Two fasteners file folders
10 of these weigh 81,6 grams so one empty folder would be 8,16 grams. The dimensions would be lightly larger than A4, it says 245 x 318mm.
Perhaps a slight upgrade to the freezer food bag...!
