Hi, I am sewing princess seams on a fitted sheath for the first time. I followed suggestions and basted, clipped, and fitted. Now that I am trying to finish it. I cant seem to sew the seam as nicely done as when it was basted. I keep getting too much fabric bunching up at the bust curve. I’m wondering if the basting stitches have caused the problem, not allowing the clipping to spread the extra fabric,or if I stretched the cotton out when pressing. I tried steaming the cotton fabric to shrink it a bit. I tried using smaller stitches around the curve but still have trouble. Funny thing is I’m only have trouble on the left side not the right. I tried to keep the side panel on top allowing the center panel to curve a bit and take up the extra fabric. My fabric doesn’t lie flat anymore like it did when I basted it. It is formed to accomodate the bust curve. I’m thinking of just trying to sew it by hand but, I really want to get this down. Please help if you have any suggestions. Curves are hard!!
