Does anyone still use muslin for quilt backing? A couple of years ago my husband and I went to a quilter's estate sale and among the many treasures we purchased two 50 yard bolts of muslin - one heavy weight and the other mid-weight - for $10 each! Since they were in my attic, they were among the few things that didn't get destroyed in Hurricane Sandy. I've been using it to piece small wall quilts and might use it as a back for placemats, but wonder if using it as a quilt backing is ridiculous. Any thoughts? The fellow we purchased it from said, "No one uses that any more ..."
