I have just come across some fun sites, so if you are looking for ideas of how to keep the kids busy this weekend, here are some great ones.
Mary Ann Ross and Kimberly Lainson at Makingfriends.com have contributed lots of fun edible craft ideas, I am sure you will find something to do in their long list.
I found another fun recipe at kidsdomain.com.
Another not-so-edible food craft is to take different kinds of fruit and vegetables and cut them in half, dip them in paint then print onto paper. You could use, apples, pears, carrots, peppers. I remember doing potato prints as a kid, you cut the potato in half, carve out a simple design in the potato, dip in paint and print onto paper. Makes for hours of fun. Whatever you decide to do, have a great weekend!
