Treasure the quilt. When I was growing up, we would have loved to have one like that to sleep under. Our bedrooms had no heat, so we had enough quilts on us, til we couldn't turn over. LOL. We used the old feather beds (which you certainly don't see anymore). Quilts then were made with what we had to make them with. Feed sacks, scraps from homemade clothes, etc. Be glad your mother-in-law gave it to you. I would love to have one like that given to me. My grandmother used to piece string quilts on newspaper or old pieces of worn cloth. Anything to make a quilt to keep warm.
