Try the Metro poly embroidery thread.. I have used it on my Janome 300E since I bought it a few years ago.. Once in awhile I'll get a shred, but not much..I always use a thread holder/heavy stand, that's placed a few inches back of the machine. This a tip I found online.. I have just purchased the box of Metro varigated..Can't wait to create with it...This thread is a lot less expensive than most...I don't want to say 'cheaper'..as it's a nice quality...
