(note: this is my first Instructable, please comment!)
Step 1: Gather Materiels
Step 2: Find a Design
Step 3: Trace It
Next, trace the design onto the non-waxy side of the freezer paper. It helps to have a light box, but I'm cheap so I go without one.
Step 4: Cut It Out
Step 5: Iron It On
When you apply heat to the paper it causes the wax to melt and stick to the shirt, giving you a perfect stencil.
(note: make sure the paper is waxy side down when you iron it on, or else it'll mess up your iron)
Step 6: Paint
I prefer to use a larger round brush, but you can also use a rectangular brush.
It is better to put on 2 or 3 lighter coats than 1 heavy one.
Step 7: Tada!
Tada! You now have your very own custom stenciled t-shirt!
