Since buying the new sewing/embroidery machine, I've known that I really need get the serger out and see if I can get it working again. Something went wrong with it about FOUR YEARS ago! I was trying to change the thread color from white to red. The tension was then off. The loops were off. I read the instruction book trying to re-thread it. Nothing was working. I put it aside and covered it up. It's sat there, lonely and unused, for a long, long time.
