I'm trying to make myself a swimsuit using my new (to me) serger. I have understood that a serger is great for stretch fabrics such as this, but when I sew a seam on scrap fabric, the seam does not stretch. When stretched, the fabric slides along the threads, and if the ends were secured, stretching would probably pop the stitches.
I did figure out how to adjust the differential so that the seams lie fairly flat, but for a swimsuit, the seams must also stretch, and I haven't been able to accomplish that.
My serger is a Janome New Home 334D. What am I doing wrong?
