Living in Florida, I've never had flannel sheets, but we do have some cold nights so thought I'd give them a try. I wash and dry them on the gentle cycle, NO fabric softener and put a cup of vinegar in the rinse cycle to prevent "pilling". So far they've been laundered about six or seven times and are still like new... no pills. I ordered a set of "German Flannel" sheets for a friend and they fell apart and left mountains of lint and fuzz all over his house after two washings. Hopefull I can return those and get him a set of these instead!
