I have to say I forge ahead. One year shortly after I started quilting I signed up for a free BOM. At the time, I hadn't realized it was a modern quilt which I don't care for. By forging ahead with it, I learned a whole lot of new things about quilting & when the top was finished & I was about to have a burning party, my granddaughter asked for it as she really liked it. So I got a backing I could deal with and quilted that side for her. She still loves it and takes real good care of it. Sometimes the lesson learned is just perseverance! :-)
