Well, I'm sensing a theme with the "stained glass" craft. It's March, so of course I had to do a shamrock craft for St. Patrick's Day. I used a heart-shaped cookie cutter for this one. Make it like you would a heart. And this is also a good opportunity to introduce symmetry as a design principle. Monkey's preschool teacher also used this idea for his class! She used green paper, but I like black, since it makes the green stand out. His teacher used a large die-cut shamrock. She taped them to the windows in the classroom. They look really cute.
A friend of mine gave me the idea for an Easter craft with a cross. We're planning on doing this for a church playgroup. Use the same concept for a bunch of other holidays: pumpkins for Halloween, turkeys for Thanksgiving, snowmen for Christmas. Older kids can even cut out the shapes as well.
Like the heart craft, you'll need construction paper, contact paper, scissors and tissue paper cut into small squares.
