Today's progress
Started out with 18 white strips, 24 green strips, 9 dark green print strips and 72 green triangles and 72 white triangles. That adds up to 199 peices to start.
Sewed the triangles and strips together, for 72 HST and 5 panels.
Then the fun - cut the 5 panels into 342 pieces (not counting scraps).
The cutoff triangles from one end got sewn together with those from the other end to make the rest of blocks.
After a few hours of trimming - I've got 324 - 2.5" blocks ready to assemble into 9 - 12.5" blocks.
