Edyta Sitar's pattern, Quilter's Patch requires precision piecing. Some pieces are cut less than an inch. I had a huge amount of trouble until I realized I needed to pin, pin, pin with my thinnest pins! I have gained some valuable skills doing this quilt--which I will never do again. I like larger pieces to work with. My scraps include nothing less than 2". Everything else goes into dog beds for the shelter.
