Thanks for the replies!
Zkimom, I know my machine felts because I felted (SHRUNK) my husband's favorite sweater once. (It wasn't my fault, though, because he tried to be "helpful" and loaded the washer himself and I didn't check to see what he put in there!!!) I was thinking that this would be a case of where something happens when you don't want it to, and won't happen when you do. I will take your advice, and will let you know how it goes.
Darcy, I always wanted a front-loader too, and then I moved to Greece and that's all you can get here, so now I have one. I like it a lot, but I can't put as much in it as I could put in my big top loader in the U.S. I was used to stuffing comforters and everything else in my top loader. I miss that!
