In a couple of weeks, I am hosting a little Halloween party for a few children at my home. I decided that Mimi and I are going to make a Pumpkin Pinata! I made one as a kid and was so impressed at how easy it is to actually make a "paper mache" pumpkin.
(And funny enough, Mimi and I were watching "Max and Ruby" this week and there is an episode where Ruby makes "paper mache" for bunny scouts, so now Mimi is even MORE excited.)
If you are looking for something fun to do with your little one, try it too. Basically you blow up a big ballon, cover in newspaper strips that have been dipped in homemade glue (1 part water to 2 part flour), let dry for a couple of days, pop the inner balloon, and then decorate by covering with orange streamer (or paint). Fill with candy and enjoy!
