This is a fun project for adults and kids to collaborate on - they get to do the designing, you, well, you get to do the work. :)
Here's what you'll need:
Craft foam, cut into squares
Some thick craft foam (I just bought a pack of the doorknob hangers, because it was more economical than buying the thick sheets individually.)
A pair of sharp scissors - I like ones that have a nice, small, pointy tip
An exacto style knife
Here's What You Do:
Have the kids draw pictures on the craft foam squares. Some of these may work better than others for this project, so let them have a blast drawing lots of different designs.
When they are done with the drawing, cut around the outside of the shapes.
Now, take the exacto knife, and gently trace over the inside pencil lines. Don't cut all the way through, just score the lines, making a shallow cut.
Glue the cut-out and traced stamps onto squares of the thicker foam and let dry.
Now you can ink up your stamps (I find it works best to tap the stamp pad on top of the stamp until it's covered with ink, rather than smooshing the stamp into an ink pad) and test them out! Pretty cool, huh? Let me know if you try it, I'd love to see pictures!
