My mom bought some curtains and inside the packages were some white corrugated cardboard. Being the resourceful (cheap!) person I am, I asked if I could have them (along with the zippers used to close the packages--possible quiet book parts!). I cut them into strips and wrote the uppercase letters on the bottoms of them, leaving enough room for the clothespins to be pinned above them. I then took 26 clothespins and wrote the lowercase letters on them (I wrote them on both sides after playing the game once). The idea of the game is to match the lowercase letter with the uppercase letter. Since my kids love playing with clothespins, this is a great game for them!
