Here's what I use. I found this idea on a site that a "frugal quilter" has. I made a few sets for myself and some for all the gals in my sewing group. They are great! If you safety pin them on, then you don't have to worry about scratching yourself! These are the embroidery floss plastic cards marked on with permanent marker. They are all put onto one of those key ring holders that you can unclip! Very inexpensive to make and nice gifts!!! You could also do by row and by block.
