I found this book at my local library and its chuck full of ways I can have fun/damage my serger . Actually I am thinking about writing my own book..............fer real! I am going to call it "101 ways to ruin you serger" I'm already on damage #2. I am making myself a new purse from some old curtains and my serger vomited it back at me, broke a needle, and now skips a thread. So I put it in the naughty chair till I feel like dealing with it!
