This is the treasure trove where you can pick the design that your quilting stitches make on your new quilt. Long arm quilting stitches the backing, batting(cottony stuff that makes your quilt soft and cushy), and the dynamic quilt top with all your t-shirts, clothing, or favorite materials together. This "edge to edge" or "all over" form of quilting secures everything so your new quilt will hold up as you use, abuse, wash, and love on it!
