Print or trace the block diagram onto foundation paper, number, and cut out as below. Important! You have to mirror the diagram if you want it exactly as in the diagram.
Baste all layers together. Baste far enough from the fabric edges to leave room for the seam allowance to be turned under.
I forgot to take photos over here...
Turn the raw edges of the center triangle under and applique just as you did with the bottom section.
Mark the positions of the remaining shapes on the block with a washable or disappearing marker and applique the shapes into position.
