Here's the play pen cover that I whipped up for ds3 (due any day now). I desperately needed a cover for our play pen as the mattress doesn't have a removable cover. I ended up with stains that I can get out when ds2 was born (see below). I used the following tutorial to make this awesome sheet. For the fabric I used minke as it's a polyester (which repels water and won't penetrate through to the mattress) but also because it's oh so soft. It's great quick and easy project that feels so rewarding!
