|Not quite happy with previous satin-edge efforts using embroidery thread in the upper looper, I thought the regular machine might produce a better result. Well, no. Needs stabilizer top and bottom and when you have to trim, you can't do the neat job a serger does, lots of hair sticking out. This is how I just did a very neat collar, and fast, for a girl's blouse. It was a one-piece collar. I cut out one collar piece, then made a sandwich with the cut out piece on top, then non-fusible interfacing and a bottom piece of the collar fabric, pinned together and rough cut (the serger will trim it anyway). It was a peter pan collar and first time around as I turned the curves, the serger didn't cover as well as I'd hoped in some areas which had been my prior experience. So I dropped the cutting blade and reserged over the original seam. Thin areas were covered, a small wrinkle I hand smoothed out was fixed and the whole satin stitch is thick and very nice. I was using the left needle, for a wide stitch. An easy, very pretty time-saving finish. The embroidery thread for the satin finish on the upper collar was in the upper looper and the tension a little looser; the lower looper was tightened a bit (to pull the shiny thread to the wrong side for a nice edge).
