Why may I ask were you acutally using such a quilt? I only get out my real old, and personally valuable quilts occassionally. Just to look and admire the work my grandmothers did. I always give directions to clean and appraisals with the quilts I do. Hand sewn not machine.
My mother in law made a beautiful Noah’s ark quilt for my son when he was a toddler. I thought it was too precious to use, so I bought a quilt hanging rack and put it on the wall. When she came to visit and saw it, she was furious that my son wasn’t using it, so on the bed it went. She is gone now, so I put it back on the rack, because it is really too precious now.
Don’t forget storing them in a cotton pillow case with as much history as possible in a zip lock bag. And refold in a different direction, inside out every 3-4 months. NO PAPER near the quilts, unless it is acid free.
