I took it apart three or four times.
The first time, I didn't assemble it right and got two blues stuck together.
So, I ripped it out.
Then I'm not consistent with my "scant" quarter inch seam. The second attempt measured 13 inches. Then I decided I'd just make a pillow out of it and start over.
Mom took it apart and I sewed it up again. I did better the third time. Got it to 12 3/4 inches. I ripped it out again and the fourth time was the charm, though I'm not happy with one of the corner pieces. It measures 12.5".
I may rip it apart again and try a new corner piece.
I've been looking over a lot of the other blocks I need to do yet and all but one of them require half square triangles.
I'm getting to where I'm like, if I can't paper piece or Thangle it, I don't want to do it.
