I had finally finished my BOM quilt top and desided I wanted the back to be in Muslin, one of my friends said that wouldn't look good, that I should go buy a backing fabric because the muslin would make it look like an old quilt not a new quilt. I asked a couple of other fellow quilter and they said who's quilt is it, yours or hers? Guess this goes under the quilter's police for sure.
