I've implemented some inset seam avoidance here again.
Print or trace the block diagram onto foundation paper, number, and cut out as in the photo.
Trim the seam allowances to 1/4".
Cut the two unnumbered sections out of background fabric, remembering to add 1/4" seam allowance.
I cut the pattern piece out of freezer paper and iron it to the wrong side of my fabric, then cut out the shape, adding the seam allowance.
Repeat for the other non-pieced section.
