Sweet butterflies! Well, lollipop butterflies, actually.
If your child likes to hand out valentines to each of their classmates, this is a great way to do it without going to too much expense. Buy any lollipops with a round head, make the 'wings' of the butterfly, and insert the stick of the lollipop into the slits in the wings. You can print out the template for the wings, but it would be just as easy to draw them yourself and then your child can decorate them however they want. If you don't have any googley eyes to stick on the lollipop wrapper, you could just draw them on with a permanent pen.
