Your friend needs to find some acid free tissue paper. It's placed in the folds of the quilt to prevent permant creases in the quilt.A cloth bag or pillow case is a good way to store an old quilt. She needs to get it out of the wooden chest. The oils in the wood will stain the quilt and deterate the fabrics. The quilt should be re-folded every few months to help prevent permant creases.
