Well, here goes. I'm going to try and do my first tutorial showing y'all how to make a freezer paper t-shirt. Actually, Jonathan did the whole thing, so props to him.
First, find a t-shirt (or onesie). From what I found, they are cheapest at Hobby Lobby. Joann's sells 5 packs of onesies for around $10. Always pre-wash and shrink it in the dryer. I'm not sure what would happen if you did it the other way, but I don't want to risk it!
Next, find a stencil. Jonathan put this one together from a few different pictures. You can draw one as well, but the internet already has great stencils.
Next, trace it on the non-shiny side of freezer paper that you can buy at the supermarket.
Then, tape it to a piece of cardboard or cutting board and cut it out with an exacto knife/razor blade. (This sounds WAY easier than it is.) You have to cut out the part you want to be painted on, so save the outline, rather than the picture. The more precise you are, the better it'll look.
Next, iron some freezer paper to the inside of the shirt to stabilize it. All you do, is put the shiny side on the shirt and move the iron (on it's hottest setting) over it for a few seconds.
Then, iron the stencil to the outside of the shirt.
Once everything is ironed evenly, use matte fabric paint and paint inside the stencil. You can find fabric paint in most craft stores.
When you're done painting, it should look like this:
Then, the hardest part is waiting at least a few hours for it to dry. When it's dry, tear off the freezer paper.
And voila! You have a brand new, homemade shirt with whatever in the world you want to put on it! (This shirt is obviously an inside joke.)
