I was just hand sewing the underside of the binding on my first quilt when I noticed that there is a 1 1/2 inch gap between my sashing and the border. The quilt is already professionally quilted which means that I can't get 'inside' to sew the seam. I tried overcasting the seam and it looked so awful that I ripped it out. Any ideas about how I can correct this error. In the future, I'll examine my work much more carefully before quilting or having it quilted. Thanks in advance for any help you can offer.
