And now....

Sewed together 24 white and B/W triangle squares, started sewing together 24 blue and B/W triangle squaress and realized they shouldn’t be sewn together the same way as the white and B/W but the opposite, and lay one out to look… no the blue and B/W are right, but then… yep… all 24 of the white and B/W pairs are wrong. 
Now to spend some time unsewing. 
Then maybe I need a nap and then start this day over?
