Pre-wash t-shirt without fabric softener.
Print stencil onto freezer paper (matte side).
Carefully cut out with an exact-o knife. Take your time and be careful!
Set iron to medium.
Place cardboard or newspaper inside t-shirt.
Place stencil on t-shirt then carefully press with the iron.
Use the foam brush to gently paint on the fabric paint. Paint away from the edges to keep from pushing paint under the stencil.
Allow a few minutes to dry, then carefully remove the stencil. If you have trouble getting a hold on the edges, use a straight pin to help get them started for easier removal.
Finish drying according to manufacturer's directions.
