I am finishing my first quilt and have noticed that my intersections sometimes produce a pucker in the fabric. I am doing the stitch in the ditch and have done all the horizontal lines first. I am now in the process of doing the vertical lines and it is now that I am noticing the puckers when my lines intersect each other. I was wondering what could cause this so that I don't make the same mistake again.
I used safety pins ever 3-4 inches and sewed it like that. I did not use basting spray or starch. I have to guide the fabric through the machine otherwise the needle just goes up and down in the same spot. Maybe I'm really pushing it too fast? Any help would be great! I think I'll probably use the basting spray and starch next time....haha
