We did a bit of a different salt dough ornament. I took a bowl and cut a circle to make a keepsake ornament instead of a cookie cutter type. The plan was to have the kids' hand prints in the circle. E (13 months) would make a lovely hand print and then dig deep enough to put holes in it. After 8-10 tries, I went to the back up plan. I think it turned out well.
My only regret is that I didn't do this keepsake sooner. Read about how to make your own Salt Dough Ornaments at my new blog.
