Lakekids - yes, I want to use a wool blanket for batting. The quilt she has only lays on the top of a queen sized bed with no drape. So I think the size will be sufficient.
PaperPrincess - The quilt of my mom's has a wool blanket used for the batting. I couldn't find a modern batting with the same weight - so I want to use a wool blanket similar to the original quilt. It's very important that the new quilt have a similar weight. Can I ask where you purchased your blanket? Did you use any other layers? Was the blanket scratchy through the quilting cottons? How did you quilt yours?
Thank you for the responses!
