I am so tickled that others are making this nap mat cover. I thought I was being origianal with mine. We have a 4K DGD and I thought of making one with blocks with appliqued items that we have enjoyed together. I will try to get a picture as soon as I finish it, but here is what I have done so far. All blocks are 12 1/2 inches square. I have appliqued: one with an "O", for her name, one with a duck, one squirrel (the hardest), one frog, one apple, one heart. Each will also have a capital letter, i.e., A for apple. I have finished all but the bright yellow sashing and the backing. Good luck.
