Today my son and I spent some time trying to figure out just how many things we could make from one empty egg carton. First we painted the entire thing, then got into the craft cupboard and got busy! We made a jellyfish, a spider, binoculars, a bird, and a caterpillar. It's fun to challenge yourself with limited supplies - like whatever you can find around the house.
TIP- when painting or crafting, use a cookie sheet to keep paints, playdough, supplies etc in one spot while the kids are working. Try to have them keep their projects on the sheet and it makes everything so much easier when you are working on a project (and cleaner too)!
