I just received a singer serger. My mother who is 90 had a serger that my sister had given to her after upgrading to a five thread model. My mother gave it to me yesterday while I was visiting her helping clean her house. She has recently been told she has alzheimer's. I started on it this morning, cleaning it as it had not been used for a really long time. It was locked up. I cleaned it to start with, them started trying to get unlocked I oiled it and kept trying to get it to move and after 45 minutes it started moving, have it started now and threaded I have stitched and adjusted and think it looks pretty good concerning the condition it was in. I am so excited now with oil all over me and dust in my face I'm a really happy sewer!
