I'm really planning to get back on the Monday-Thursday schedule. Really.
Another block with teenie pieces. What is it with row A?
Print or trace the block diagram onto foundation paper, number and cut out as in the photo.
Foundation piece all the numbered sections and trim their seam allowances to 1/4". Cut the unnumbered triangles out of fabric, remembering to add 1/4" seam allowance to them as well. I ironed them onto freezer paper to stabilize them and make it easier to cut the seam allowance.
Assemble the 3-section side strips.
Sew them to the center strip.
Sew on the side triangles one by one, following the diagram.
