I just finished a similar quilt in December for my future daughter-in-law. It’s a half log cabin block but I’ve seen the pattern sold as a Bento Box Quilt. I must be stuck on log cabin quilts, this is my 3rd variation in the last several months.
Jeanne’s Mystery Quilt looks different than my scrap version. I think hers has a more graphic look and she’s right that it goes together really quickly.
