This is a mini tute, there are a million out there, so don't hesitate to check some of those out too.
What you'll need:
shirt or other fabric (maybe a tote, make sure it is pre-washed before you begin)
freezer paper (different than wax paper because one side has wax and the other is plain paper)
stencil idea (handmade, internet image, etc.)
paint brush or sponge brush
puff paint or other type of fabric paint
exacto knife or sharp scissors
cardboard (i used a paper bag) to keep the paint from bleeding to other side of shirt
This is a link to the Scooby Doo pattern I used. (My boys are currently obsessed with Scooby Doo, I've recently heard more"Jinkies", "Zoinks" and "Jeepers" than any mother should be forced to endure).
I cut a piece of freezer paper large enough to cover the pattern with a little extra around the edges to keep the shirt protected.
Luckily the freezer paper is thin enough you can easily trace your design if, like me, you cheat and print a copy from the internet.
Next you're going to want to put your cardboard or paper bag between the t-shirt layers. This keeps the paint from bleeding through. Grab your brush and paint, and you're ready to start the fun part!I painted on the first layer and quickly realized I would need multiple layers. So depending on the saturation you're going for, you can leave it with one layer, or go for four like I did. The first pic has one coat, and the second one has four.
Ah-maze-ing! Can't wait until the munchkins wake up from naps and see the finished product! Have fun folks!
