When I zoomed in on the print it looks kinda retro or vintage.
Wow! Cool! I have read that when utility quilts go ragged from use, they covered it kinda in duvet style. Looks like someone didn't like the raggedness and stain and started to do just that. After all, it would still keep one warm. The orange fabric if it isn't part of the old quilt and of decent quality could be used in blocks for a fall or halloween quilt.
Bless you hubby's heart, he thought he was doing good! He was!!! lol
