Calculated various backs for the scrappy blue 15 minutes of play quilt. Three options, of varying fiddliness. One looks like a Union Jack so that one is out. Another requires 8″ blocks that are in base five, so that’s a different kind of fiddly. Plenty of time to decide as the top isn’t even finished yet!
Made a couple of blocks for the guild lotto at the next meeting. Link has the tutorial.
