Now it's time to secure the stencil.

Carefully place the freezer paper stencil on top of your hoodie or shirt, wax side down. Once you’re happy with your placement, take a hot iron and press it directly on top of your design. Don’t move it back and forth, like you would if you were really ironing something, just “stamp” it over all areas of your design, pressing a few seconds at a time, until it’s all pressed flat.

With the wonders of freezer paper, the wax side will bond securely to your shirt, but when removed, will leave no residue.
