I do not think it is ugly at all, I think it is wonderful, and thank you for sharing your story, I am glad your dad got it back.
And, yes, I have a polyester quilt a family friend had given me, I am going to be putting a simple sheet backing on it, I too thought it was "ugly" but as I look at it, I really do like it because of the time and love that was put into, and I like alot of the older quilts anyhow, it takes me back to a time I wish I lived in and makes my mind wander and dream I suppose, if that makes sence. But I can not wait to get mine done and put it on my bed.
