This work of art is a great craft for children to have fun with. Materials for this particular project are 8 x 17 canvas, colored cardstock, butterfly paper punch, and hot glue. Simply punch the butterflies, measure and match up before you glue. Score the cardstock down the center and hot glue along the seam. I lined mine up lightly with a pencil and erased the marks after the glue had set. This would also be cute with other insect designs!
