fake pumpkins

Hi all! I have a few fake pumpkins my daughter decorated when she was much younger. She doesn't like them anymore, so she wants to redecorate them. Some have modge podge on them and some have glitter. What is the best way to remove this stuff? Can I sand them with sandpaper? Thanks. julie

Can anyone give me any leads on where to buy funkins this time of year? Foam, carvable pumpkins. Found some 2012 info and Funkins is the brand I feel I should be looking for. I got really good at carving and want to make something that lasts. Paid a small fortune for some at Michaels crafts...
