Several blocks were too wonky, and to make them all consistently the same size, I chose the smallest dimensions. They are now 12.5 x 11.5. I changed the orientation as I trimmed just to see if I like it this way:
And here one of the blocks trimmed up. After I sew the sashing, the height of the top & bottom wedges are going to be shorter than the other mountain peaks due to the trimming.
I’m older and wiser now . . . lessons learned:
— Measure my piecing right away and redo if necessary
— Don’t let my UFOs sit for 15+ years in the garage!
