I always thought the better the quality the less it pilled. But from reading some of the above posts, I guess that is not the case. I have a couple of Moda flannel quilts that I made several years ago, maybe 7 or 8 yrs., they've been washed several, several times. The nap on the flannel is GONE, and now feels like soft soft cottons. I don't think they ever pilled up.
