Some scissors and clear tape helped me transform the homemade rattles into homemade photo rattles (and a photo lid for chewing). I saved the Christmas card after all! Little Lady had the most awesome grin on her face when I handed her a couple of the rattles, like, "Hey, I know these people!". We played 'What do you choose?' and she had fun shaking her brother around. She laughed pretty hard about that. It was also funny to make a stack of faces and knock it down.
So, the photo rattles are a definite success and I won't feel bad when I eventually get rid of them... talk about re-purposing things!
