I just finished a mystery BOM that didn't really like. I just kept plugging away since I had made all the components for it. I did end up ripping apart one block because it REALLY looked out of place, and added an extra border on the top & bottom. Then I put 2 more borders on it to help tie in the colors. In the end it turned out OK, and remember someone will find your quilt perfect for them-time will reveal who will be the ideal recipient. I think your pattern & colors are great.
