This was my birthday present from my eldest daughter! She found it on pinterest somewhere, snuck off to the craft room and whipped them up.
It's made from a quilting pin, a letter bead, and a small silver bead. They are hot glued to each other. We didn't have any number beads (but they do sell them at Hobby Lobby), so she used alphabet beads. I have already been using them for a quilt that just happened to have the rows marked with letters!
If you make these yourself, make sure to use long pins. These are a little too short to go through multiple layers. But they are still pretty awesome. No more sticky notes for me!
