I think the other comments have covered it. We did it 2 years ago at our halloween party, 8 kids sitting round the table. Put down a BIG drop cloth or plastic shower curtain, we used tempera paint to paint them. You can buy an acrylic sealer to put on them after they dry. You can do stencils or any of that if you want. I just gave the kids some mini pumpkins and lil gords, and said have at it! they had a blast (there were 2- 5 year olds, 1- 3 year old, 3- 6 year olds, a 7 year old and a 9 year old). if you want to you can put forth some money and buy mans white t-shirts and put them on the kids to protect their clothes. and you can use permenant marker to put thier name on the bottoms of the pumpkins. remember to take lots of pictures, it's Fun!
