I have never seen or heard of a bead spinner, but this looks like something I would truly love to play with. Threading beads and controlling beads for projects is a chore. This little gem looks fantastic.
It is also made by Darice, a brand most of us trust.
FaveCrafts is giving this one away. You can go to their site to enter to win one of these handy tools for beaders. The reviewer gives you some great details.
