Puckering Paper Piecing Seams
I've started my first paper piecing quilt project and I'm hoping someone here can help me solve a problem. All of my seams are puckering. I am sewing with a Janome 15000, stitch length of 1.5, Aurifil thread, a 70/10 needle, batik fabric, and the pattern is on newsprint paper. I've tried an 11 and 14 needle, reduced the tension all of the way down to -3, and rethreaded my machine and bobbin. Nothing has helped. When I sew a regular seam on a piece of scrap fabric, it's fine. Is it the paper that is causing the problem? Any suggestions?
