So here is my latest creation. I made the tiles some months ago but couldn't decide how to join them together. Every now and then I would get them out, play with them for awhile and put them back in the "to do" box. I thought about putting loops on the backs and stringing them on waxed cord with knots in between but was concerned they wouldn't hang right. I played with the idea of loops on the back and then string on black rubber cord with "O" rings in between, again not sure they would hang right. I finally decided this would work and it does. I like the silver rubber cord better than black, don't you?
