I absolutely LOVE chair pockets! Between textbooks, spirals, folders, library books, and all the other supplies-there is just not enough room for everything in the desks. I don't know what I would do without them. But, I'm thinking it's time for this set to finally retire. Making new chair pockets is going to be this summer's project. They really do last a long time, and mine are made of ordinary fabric. This was my eighth year using the same set. Replacing them every 8 years really isn't too bad!
