I had an old Singer serger and never used it because it was hard to thread and adjust for different types of sewing. I sold it in a yard sale and bought a new Baby Lock Evolution. It is wonderful. If you do garment sewing it is a must have. I don't however use it much for making quilts. Sometimes I have used the wave stitch to bind quilts. It looks pretty, but won't last as long as regular binding. They are expensive, so I would make sure I would use it enough to make it worth the price before buying. Mine is mostly used to make clothes for the granddaughters. It does such a nice job on dresses.
