Next sew together a Color 1 and a Color 2 2-1/2"
x 20" strip right sides together along one long edge. Press
seam to darker side. Bisect this at 2-1/2" intervals to get eight
pieced units. Now flip alternate units and sew pairs together to form
four Four Patch units.
Sew a Color 1/Color 3 pieced unit from the step above to the left
edge of each four patch unit to make four Unit A's. These should
measure 4-1/2" x 6-1/2"... on to Page 2!
