Thank you all for your kind words and tips for the backing. I already ordered backing fabric from a local quilt shop and am patiently waiting for it. Quilter's Club of America will be holding another mystery "Mystery Quilt #12 in a few weeks and Connecting Threads is starting one tomorrow. I signed up for both and will use the fabric for those. I do love these mysterys it keeps me motivated and they go for good charitable causes. A win win for us both.
