I made these just now with the kids all running around crazy playing dress ups and planning a "show." Apparently the show includes tickets, a super dramatic red head, a bossy little ticket maker, and a cousin who's torn between which kid to listen to. (I only tell you this so you know how easy they are)
Materials are easy- Felt sheets (around $.40 each) Embroidery Thread (around $.40) and needles. Just cut out your first heart, make a second one just a bit bigger, and do a running stitch around the edge. I just hot glued a snap clip to the back.
Super easy, cheap and cute hair accessory for the next few days. :)
