Does anyone know where I can get some acetate sheets? I've tried Michael's, JoAnn's and Hobby Lobby. Even though I've asked at all of those stores (and the answer was always "I'm not sure"), I'm guessing it's such an obscure product, the average clerk might not even know if they had them. Anyhow, I don't want a lot of them... maybe 5-10 sheets. Anyone have any suggestions? Once again, thanks for all your help.
