I try to do some sort of craft activity with my girls a couple times a week. This one was successful as it's not easy coming up with something a 2 yo and a 4.5 yo can both do without me needing to have a lay down afterwards. Items used were clear contact and scrap paper and fabric which had been cut up.
I drew a simple butterfly on one side of a small piece of contact, and folded the backing paper back to reveal the image. The girls then placed small pieces of paper and bits of fabric within the butterfly outline. We then pulled off the remainder of the backing paper off and folded the rest of the contact over covering the butterfly image.
I then cut around the butterfly outline, hole punched and then tied them to a stick to make a simple mobile.
