The foundation makes the blocks very thick. I'd already fought that thickness on the Watermelon quilt so this time I added a half inch sashing. Now the thick string seam allowances meet exactly under the narrow sashing. No pressing problems this time.
I used two different post colors (orange and yellow) and varied the sashing with the side of the block. Cute, done, off to college in the right color!
Fret not; enjoy the day.
