I'm making a big (about 110" x 99") string quilt, sewing the strings onto muslin squares so it'll be heavy. Dogs and cats will sleep on it as we sleep under it, so it's going to be a hard-working quilt. What would be best to back it and/or use for batting? I don't plan to quilt it any more than necessary. Should I skip batting and just use fleece for backing? Does that work? Would flannel as batting and basic backing stuff be better? Or---?
TIA
