Just for a refresher, here’s the link to the Creative Grids Wonky Log Cabin ruler.
In the picture below (photo credit Creative Grids) you’ll see what I’m describing as the trim lines being dotted versus solid lines. If only that last line had been dotted! My brain was fully trained after so many rounds of trimming based on the solid line that the logic that the ruler didn’t actually end there never wormed its way into my brain. Surely that should be written up as some sort of psychological test somewhere. “How many quilters will stay fully focused on the solid line even when all logic points in another direction?”
