While it looks complicated, I got my friend Gail to print out a foundation pattern from EQ6 to the exact size. This helped me avoid the possibility that the templates weren't the right size.
And I like to paper piece, so it worked up relatively quickly. I stuck all the pieces to my portable ironing board with applique pins so they wouldn't blow away with the overhead fan on.
Only one more pieced block and two applique blocks to go.
