A couple of weeks ago I picked up a Singer Overlock at an estate sale. It has the directions, extra needles and thread. I even got some more thread at Joann a week ago. Here's the problem. I am so intimidated by this thing. Just looking through the manual made my head hurt. My son was kind enough to thread it for me, but now ... eeek! I'm terrified of it. Too many tension dials. Too many options. Help!
