I bought a Singer serger at a flea market 2 years ago. I just got it set up and am using it and LOVING it!! Can't believe I waited so long to try it out. I have the Operating manual, that shows me how to thread it and clean it, etc. but it does not go into detail. I thought I had another instruction book, but cannot find it. Unfortunataely, we moved during the time period, so it could be almost anywhere. Does anyone have this manual, or know where I can get it? I found it on the Singer site, but it was the same thing I already have. What I am excited to know how to do is make gathers. All the manual says is to change the differential feed on the bottom. I did this and it did not gather. I figure I need to be using a certain needle and maybe less number of thread? I have it set up with 4 spools. It has both needles in. Any help would be greatly appreciated!! Thank you.
