If you lived through the 80's you remember these. I found an archived tut for them. I made so many of these in the early 80's! I'm going to make some red and green ones for my next show and see if any 80's mom's buy them!
This is a great craft for kids to do with you! http://web.archive.org/web/200512252...aidbarrett.htm
Oh, and I've seen the barrettes at Wally World (Wal-Mart)
