Just finished a BOM for paper piecing from Amy Gibson (Stitchery Dickery Dock and Craftsy); she sews the line with a 1.0 stitch with no thread in needle before beginning to sew the fabric on, she then folds line lines up fabric and sews on the line. When the block is finished the paper will easily tear off and not leave pieces behind. This made it so easy to piece together, I have done it other ways and thought I would never do paper piecing again. The Craftsy sight has her 2012 BOM (free) and video demonstrates procedure perfectly.
