I have had a Singer serger for about 20 years. I have used it a lot. I especially like it to serge the edges of quilts after they are quilted. I use a four thread overlock stitch. By doing so, the edges are automatically trimmed, compressed and stitched together resulting in a nice, even edge. Our guild makes twin sized quilts for wounded soldiers. I have, as of yesterday, quilted 211 of these quilts on my longarm and have serged the edges. The quild ladies that sew the binding always tell me how they love the serged edges. I have also made boo-coodles of pillowcases. The serged seams make a wonderful finished seam.
