Recently I sewed up 8 fleece diaper covers. Fleece is known for being a good night time cover because it is very water proof, but also breathable. After three nights use I have found this to be true. It even lasted out Elias with no leaking or wicking. I was able to make about 3 covers from 1/2 yard fleece. I got the fleece for 40% off at Joann's, so each cover cost about $3. Very affordable for something that works so well! Plus, the cute fleece prints look absolutely adorable!
