I was sewing this poly knit that only has a crosswise stretch when I noticed that the stitches were all in different lengths. I got a new ballpoint needle, but that did not solve the problem. I checked my threading a million times and checked the bobbin and tensions, but it still did not work. Then I sewed the fabric diagonally and the stitches were perfect! I can't sew my blouse diagonally and the pieces are already cut out. Does anyone know why this is happening and what I can do to solve this issue?
Any info is greatly appreciated as I have a line to create for a show!
