I recently did a brown quilt (just tan and dark brown) put it in my mid-arm quilt frame and really whipped out the quilting. As I rolled the quilt (that left about 36" left to quilt) suddenly I saw that my quilt back was going to end about 18" short!!! I had pieces of the tan and dark brown that were each about 4" wide. I took the quilt loose from the frame (on the unquilted side) unrolled enough of the quilted portion to pull it down far enough to hang off. Then I sewed all of those 4" strips together put my sewing machine on my rolling sewing chair and sewed that extra piece to the quilt back - rolled the quilted part back on and reattached the quilt back. The whole point of the story is my customer thought it was wonderful. The quilt was 108" square. She puts the pieced back at the top - turns it down and tops it with pillows with dark brown cases. Sometimes a mistake turns out to be awsome!!
