I tried restoring with the silk tuelling ($75.00 a yard) and it did not look good. So I found some 30's fabric, made a template and put new fabric (matching) over the old one by appliquing(sp) and then re-quilted the same stitch the original was. Once you put new binding on it takes away the value and year of the quilt. So when asking my customers what are their intentions, that is how I make my decision on the repair.
The tuelling made it look chincy and the new replica fabric gave it charm. I buy enough to make future repairs. quilter_kjm
