My neighbor just gave me a Baby Lock Serger with a big box of Wooly thread, and extra feet attachments and a whole bunch of other things I don't have a clue of what they are. His wife past away and this was her's. She had just bought it. I have been sewing for years but never with a surger. So I will be joining you, Piney River, playing until we learn how to use this crazy kind of machine. What is Wooly Thread anyway. Can you use it other than Serging?
