It must be a summer thing but I seem to always be a day late these days.
This block looked kind of time consuming but once I studied it a little closer it ended up being very, very simple.
Print or trace the block diagram onto foundation paper, number, and cut out as in the photo. (Click on the photo for a larger view since this one is not all that clear.)
Software users remember to change the block size to 5"x8" before printing.
Foundation piece all the numbered sections. Trim the seam allowances to 1/4".
Assemble the block referring to the block diagram.
I know there's a little extra triangle at the top. You can just applique that on but I think I may leave it off because the block looks so nice and clean as is.
