I made these from old CD's. One or two of them were made from the clear CD's that come one the top of the package of new CD's. I cut a round piece of felt the same size as the CD and glued it on a CD. Then I used a die cut machine to cut out felt pieces that would help tell what was created on that day. The kids put the pieces on the felt CD as you tell the story. The neat thing is that they all stack up and store very easily.
