I glued the A & B pattern units to card board stock and cut out.
Cut 6 1/2" strips (WOF) from both the white and med-dark fabrics. Placing the "A" template on the strips and traced. I was able to cut 8 units per strip. What you don't see are the two layers of med-dark under the white.
For the "B" unit, use 4 1/2" strips, same method --- trace and cut.
Now -- a closeup of the TWEEZERS -- my favorite tool. I notch the curved center of both A & B units. starting from the top, I sew VERY slowly and if I am "off", I will see it by mid-way (the notches need to line up midway). Admission: "I did have to use the ripper 3 times"! Not bad on all the ones finished.
