That is one of the coolest teaching tools I've ever seen!! Yep, this proves it, quilters make the best teachers!!! (Amongst other "bests") Lucky kids you're helping my friend!! Wish there were more teachers like the wonderful ones I've met on this board!! What great shape our school systems would be in then!!! Ahhh to dream!! Thanks for sharing...the girls said that you deserve a big ole "A+" for that one!!
