Every quilt has at least one flaw, only God would make a perfect quilt, I say patch it the best you can and finish it...if the lady doesn't want it after it is patched, I bet there is someone out there who would love to buy it, patch and all...you might have to lower the price becasue of the patch, but Dresden Plate patterns are so pretty they always have an appeal...post a picture, I may even be interested in buying it.
