I wanted to make a memory game for my grandkids, but I couldn't find quite what I was looking for until I looked around and found Woodpeckers. The discs I get from them are not only the right size but they're more consistent in size and better quality than I found anywhere else. I enjoyed working with Woodpecker's products so much I started making more to sell. Thank you, Woodpeckers! The larger discs are for little ones - two of each color. Right now my granddaughter thinks they're delicious. The smaller ones are from variations for bigger kids - Musical Instruments, Bible images, Playtime, and Insects. I'm working on putting together other sets like foods, animals, basic shapes, and a few others.
