Reddit mentions of Fiskars Fingertip Swivel Knife

My process:

• Wash and dry shirts before anything else.
  
  
• I use an X-Acto knife to cut out my stencils. Note, I still use freezer paper. I just ordered one of these to replace my standard knife.
  
  
• Make sure shirts are nice and flat when you iron the freezer paper onto them. Any small bumps or creases could allow leakage around the edges.
  
  
• Let your iron heat up for a few minutes before using it, it makes a huge difference. Also, no steam setting should be used! You want everything to be dry.
  
  
• When ironing, I start from the center of the design and work my way outward. This decreases your chances of having bubbles in the paper.
  
  
• Iron the freezer paper on for at least thirty seconds.
  
  
• When you are ready to spray, get a piece of cardboard and place it inside the shirt, directly behind the design. This helps prevent the bleach from soaking through if you are doing a one-sided shirt.
  
  
• Many people use a 50/50 or 60/40 mixture of bleach and water. I use a slightly stronger, maybe around 75/25 mixture. Be careful though, it may damage the shirt if left on for too long.
  
  
• Before spraying, I lay old dish towels around the edges of the stencil to block over spray from outlining unwanted edges on the shirt.
  
  
• When spraying, I have found this to be the most helpful. Forget adjustable spray bottles or brushes. I haven't had any luck with them. Think of this, when it rains, a nice gentle rain soaks the ground well. A rushing torrent of rain yields high amounts of runoff and erosion.
  
  
• Spray a little bit from a height of around 8-12 inches (20-30cm), let it sit for a few seconds, then gently dab off excess with an old dish towel. Do your best to prevent the bleach from soaking through the freezer paper. This will ruin the shirt. If you spray too heavily, it soaks in around the edges and you don't get nice lines. Repeat spraying until you get your target color.
  
  
• To rinse, have a 5 gallon (~20 L) bucket of water mixed with a little bit of hydrogen peroxide. The hydrogen peroxide mixes with the bleach and yields salt water and oxygen gas, which stops the bleach from reacting with the shirt. Dunk the shirt in until soaked, then peel off the freezer paper. The water should loosen it quite easily.
  
  
• Wash and dry the shirts again, and voila! You have nice new shirts.
  
  
  I hope some of this helps. My first couple shirts weren't too great, but experimenting has given me the process I typed out above. If you have any other questions, don't hesitate. :)
  
  EDIT: Formatting.

This is the same size blade and also swivels, but I much prefer the hold on this knife compared to the straight handled knife. It never makes my hand cramp up.

Thanks! I used this Fiskars exacto knife, and a metal ruler when I was cutting. :-) At some point, I'll probably buy the swivel version.

wowza, they're all so intricate; i'm glad you have found a way to profit from your work. but how do you repair an area that you accidentally cut through, or off?

also, check out this tool - i found it's design handy when working for a long time, especially on the more curvy bits.
