Skipping zig zag stitches, sewing a Bailey Island Hobo Bag
Am making a Bailey Island Hobo bag, I have changed to a 90/14 needle and done everything, but am finding the zig zag skips on the left side here and there. Enough that I have to sew over it again, to make sure there are no gaps. Any suggestions what I could do. I took machine in to dealer, he adjusted the needle, said the screw was loose.
I do think if I can finish this, it will be the one and only one I sew. All other sewing does not cause me problems like this.
