I have a Singer Touch and Sew Zigzag Deluxe Model 625 which I recently had serviced.
While talking to the technician, I learned that there is a foot for that machine that you can use for overcasting seams. I purchased one but don’t know how to use it.
This is what I do: 1. Put in my zigzag throat plate 2. Do my settings for zigzagging, and 3. Attach the overcast foot. I also adjusted the tension as I am trying to overcast a sheer fabric.
The result is a plain zigzag stitch — NO locking stitch. What am I not doing correctly?
The foot looks like a regular straight stitch or a zipper foot except that it has a little pin on one side (I guess you can call it a looper or something like that). Is my problem in the threading? Has anyone out there used this foot before? Thanks for any help you can share.
