OK now my interest is peaked.
I have a Singer Ses 2000 all in one machine. It sews, serges, cross-stitches, auto punch, embroidery, photo stitching but have used it only for embroidering so far and got it for that feature as well as photo stitching and sewing but now I think I will play with it for serging and see what happens.
I use a Brother and a Janome for sewing/quilting.
