I've always been drawn to Rag quilts, and this one you made for your niece is colorful and unique. Thank you for showing it and the explanations of how it was made. As I understand it, the denim was used as the foundation and you did a "stitch & flip" with the quilting cottons, the stitching lines becoming the quilting. Is that correct? When putting the blocks together, do you stitch twice for re-enforcement?
