Here's the problem. when I moved, my sheets didn't come with me. DOH! I am over flowing with cans of refried beans, spaghetti sauce, apple sauce, and more. I want to dehydrate them (saves space and has a much longer shelf life). What is best to use to make my own sheets? Stopping at Bi-mart they are always out of the sheets, and when I asked for them at my local walmart they looked at me like I was from mars.... So, rather then spend $8.00 for 2 online, I thought I could try making my own. I thought of wax paper, but am worried about all the melting wax.. I thought of parchment paper, but I don't have any. (it's over an hour to drive to town.) I thought of tin foil, but I am worried about air flow blockage and the foil raising the heat too much. Any ideas?
