I'm trying to make what should be an easy skirt -- an a-line mid-calf skirt with an elastic waist, back darts (trust me, I need them) and an underskirt. But I can't get my stitching smooth.
The fabric I'm using is a sheer, lightweight, flowy 100% polyester. Because it's sheer, I'm planning a solid underskirt in a similar fabric that's a bit heavier and not sheer.
I tested my thread (dual duty) and tension on some scraps of each fabric, and the puckering on both was terrible. I've dialed my tension down to almost zero, and the puckering is still terrible. It's definitely puckering on the top.
What should I do? Could changing my stitch length help? I am using a brand new needle.
I almost feel like I need a walking foot (which I do not have), but it doesn't seem like the two layers of fabric are slipping.
