Unless you know you are REALLY going to use one, I say to just stick with your sewing machines. I have both a serger, and embroidery unit for my machine which are next to new. The serger I used for a jeans jacket, but never have made another, it sits unused. And the embroidery unit I only used in the class I took on how to use it...which was years ago, and I haven't used it. Maybe if I had girls instead of boys I could use it on clothes? I guess I got deals on both of them and THOUGHT I would use them, but my preference really is quilting...and just don't do other sewing. Maybe someday?? I keep thinking I should just sell them.
