Hi- I have 2 sergers...one for coverstitch and the other for most everything else. They are both Husqvarna Vikings 936's and are computerized with 23 different stitches. They do hems, cording, ruffles, rolled edges, etc. They are great for tableclothes, clothes, pillows...I even made a quilted tablerunner with mine. I don't feel the serger is good for piecing where you have to be conscience of that 1/4 inch and starting/stopping on a dime. Hope this helps:) / Lissa
