Julia, my sister-in-law suggested the microwave to demo them as well. Thanks for the tips.
Bear: in answer to your questions: vendor fee is $35 and that much is a donation to the booster club. I get to keep the rest. I'll look into the cost of small pillow forms. I thought about regular size pillow cases for kids since I have a lot of fabric for kids, but not sure I could get enough for them. They aren't licensed ; I bought it for donation pillowcases but they are kid-friendly prints.
My son who is 17 uses a My Pillow travel pillow for sleeping. Well, he was, until our dog chewed it. Now I have to repair it!
