We are warned over and over about the potential damages to quilts stored next to wood and non-acid-free paper. I wonder if quilts made with wood-pulp paper for piecing will ultimately be degraded from contact with this material. It would be good insurance to always remove the paper.
In older days, sturdy paper was a rag based product; linen and cotton were the raw material and so patches found with the papers intact were not damaged. Does anyone really want to take a chance with cheaper paper?
