I have holes in my customers quilt. I had to frog some of my piano keys and now I can't seem to get the holes that the needle left out of the fabric. This customer doesn't wash her quilts and she wants to show this one. I have tried getting it wet and rubbing my fingernail over the fabric and then letting it dry hoping that the fabric would shrink some and close the holes and it did with some of them but not the majority. Any ideas? Please?
