I have not been keeping up with Dear Jane, because Dear Cyclone is taking up way too much of my time. She is endlessly fascinated with string theory, and when she gets tired of playing fast string, she settles in my lap for some slow string theory.
At first Dear Jane block C10 or Patriot's Corner looked daunting based on the diagram and Jane's piecing. However, if one reduces the seams to what's only necessary for the pattern, this block reduces down to strip piecing with flip triangle corners.
For the scale of this Dear Jane block, the strips are cut 1 inch wide unfinished. I made two sets: a two strip set and a three strip set.
I also cut five 2 inch squares of background. One is used for the center, and I added a one inch flip triangle to one corner of each of the remaining four 2 inch squares. I cut the two strip set into two inch sections and the three strip set into one inch sections. Laid out, you can see the block coming together.
Once the strip sections are sewn together, the block is reduced to a nine patches.
