The sender mystery has been solved and I've thanked her. As suggested, it did indeed come to me from a comment I made about a quilt she had made with this fabric. It was such a surprise and a delight, we laughed together over the joy of the gift!
It will be a while before I get to work on this as I'm in a bit of a holding pattern right now, emotionally, as I wait for the thyroid surgery upcoming June 22. I promise to share it when I've got something!
