I have a chance to buy a used Husqvarna Viking Serger mjodel 905 for $400, with a box of feet. I have never used one and thought I don't need one, but my DH says I should check it out! I piece quilt and do some sewing for my grandchildren. Should I be using a serger to piece my quilt tops? Seems like extra work (?) Thanks for any help and insight you can give me. This is a great group for information and help!
