I agree. Ask your LA'er how much extra fabric she wants around the backing.
Iron the top and the backing.
Remover any pet hair and stray threads.
Roll the batting. No folding creases if possible. I recently received a quilt to do and the backing was more poly and it was awful trying to get the creases out of the backing. Nothing I did helped much with the batting. I wonder how long she had had it tightly folded and where.
