QHelp! I need more bobbins for my sewing machine, but they all look alike in the store and online. Does it matter what size I get, and if so, how do I know which ones to buy? -Harriet Brown, Greenwich, Connecticut A Carol J. Fresia, Threads' senior technical editor, has gone round and round on this issue herself: It definitely does matter what size you use. The wrong size bobbin can cause jamming, poor stitch quality, or damage to your machine. Start by checking your machine's manual. The bobbin size and type should be listed there. If it isn't, but you have one of the bobbins that originally came with the machine, take it to a local machine dealer (preferably one who sells your machine brand) and ask for the same type.
