S.D.
We don't do party favors. But, I've done things like make playdough to play with and then take home, or a craft kids can put together and take with them. The playdough was a great hit at my son's 3rd birthday party. I made small batches in the colors the kids asked for. Then you just keep it in a zip-lock bag or tupperware container and it lasts forever! It's super cheap too :)
