I tried several things. Din A4 transcparencies + adhesive spray are nice. Did my Sivir shirt with them. But they are hard to cut and I wanted something where I could cut on the shirt so I could remove layers from instead making one stencil for each layer.

Then I tried bookwrapping foil. Very nice for making one layered stencils. Can even used a second time. Not so nice for making multilayered ones.

I even tried normal printer paper. The results werent that bad.

I dont know. maybe im just not used to Freezer Paper yet.
