My gf made these years ago and used to sell them for $3.00 She used to make a lot of money selling them. She would take orders. She worked in a school and sold them to the teachers and their friends.
I got the directions out of Good Housekeeping zillions of years ago, and I still have them. If you want them, send me a PM with your address and I'll make you a copy and send it to you.
