I've been collecting down-filled pillow forms over the last year and finally got around to finishing pillow covers for them! I've found that with kids, it's a must to be able to take the covers off and wash them, but I don't like the envelope or button closures because they shift around too much on the pillow. I use invisible zippers on mine. I know the word "zipper" freaks some people out.. but trust me.. it's easier than you'd think (and that's why I'm showing you how)! I also add a lining...
