Tell us about yourself!
I had quite a good experimentation with this, using printing paper and envelope paper(is that airmail paper? I don't know, we don't have quite a good translation of that in hebrew, my native language) with white trashbags I took from work, and had quite the same quality of results... Although all my stencils were not reusable unlike acetate made once that I easily peel off the fabric, not sure if it is the designs which are quite detailed and docile/sensitive or the paper itself. still quite a good method for DIY designs and for a "perfectionist" like me who really cares about the bleeding and the fineness of the result :)
