I could not visualize paper piecing in order to do it for the longest time. This young lady explains it so well that I overcame my mental roadblock. She moves a bit fast but just pause and try along with her, or back up and listen again. She throws in some neat things to keep track of the process. A couple of things I wrote down and refer to as a check list. I know it is basic but mundane trips me up every time! 1. Wrong side of paper pattern and wrong side of first piece is the most important for me to remember for things to go smoothly. I also would put a pin a 1/2 in beyond the sewing line and edges of piece going to sew. Then when I flipped to put the next piece on, I knew it had to at least butt up against the pins. The pins are for guiding not holding anything together. I DID it this way until this young lady shared her little technique. Bright girl.
