Alright I uploaded some pictures on Imgur to get you started!

Quick tip: I'm using a middle size cloth, there are different sizes to buy on the store , you can have small sizes which itself will affect the size of your cross stitch. The smaller they are, the smaller size you'll get. The brown lines you see by the top is a guideline for the stitching: each line is 10 squares, on some patterns you find there's going to be a square, the square will almost always be 10 squares big.

You'll usually find cross stitching everywhere on Pinterest which to me has been great! If I for example end up on a site for the alphabet in cross stitching I found that there are so many different and beautiful letters you can stitch as well, so I added an example of the K I'm going to stitch underneath. There are also a lot of different edges which can be simple, or complex, just remember to use the 10 square system for the patterns to see how big of a size it'll be for your bag!

When you get cross stitching yarn, you'll notice that they are very thick while mine is not. That's because I split the yarn into having 3 strands when I stitch (they usually come in 6 strands so it's just split in half) while the outline I have on this key is just one whole piece of the yarn.

The process of stitching can be very long if you plan on stitching a cross every time so I have a little video that I would recommend you to watch once you get used to the stitching, it'll really come in handy for bigger pieces like this : youtube

As you may notice, the color I'm using is different to the key on the pattern, but that's also what makes mine feel a little more unique than going fully for the pattern itself. I inherited a lot from my grandma when it comes to colors and needles, but I'll advice that if you get the tiny squares, get a smaller needle BUT not too small because it depends on how you are going to deal with the thread, the more strands of thread the bigger hole you need for the needle and usually the smaller ones would only allow you to fit 2 strands.

I DO recommend you check amazon or any kind of site that sells the threads in a rainbow set (something like this )because you do need to use a lot of different colors when it comes to stitching, and there are some sellers that will sell you a frame as well in the price (I'd say about 10-15 dollars which might sound a lot but usually you get ALOT of colored thread to that price.

Now here comes the creative tips that some people would love or hate:

You don't have to be "traditional" when it comes to these kinds of hobbies, especially if you're aiming to satisfy a gamer for example.
There are so many different designs in the gaming section to do!
Pixel art! You can take any pixel art you find and create it depending if you have he colors. You can make pokemon for example. The pokemon index on the web is one of the things you can look for and make all of them. Then there are final fantasy summons and bosses
If none of that inspires you, there are character creators on the net to make your own pixel character as well.
I'd also recommend cross stitching softwares that can turn images into cross stitching where they usually tells you the colors you need and the size you need.
I highly recommend checking the cross stitch community on Reddit as well.

I hope this inspired you.
