Those are both great ways to make cheap and easy spinners. However, if you would like to get a hold of some good spinners, lately I have been using these.
They are very reasonable. That’s a pack of 5 for $12.32, and, if you have Amazon Prime, you get free shipping. I simply tape the spinner to the top of a cd case that I purchase at the Dollar Tree and place the spinner card inside the cd holder. It’s a simple change out system.
