Next, cut the Color 1 and Color 3 2-7/8" x 23" strips
into eight 2-7/8" squares. Stack one of both colors right sides
together and draw a light diagonal on the top square. Sew 1/4"
away from the drawn line on each side of center. Cut apart on the
drawn line. Each square will give you two half squares. Repeat this
with all the 2-7/8" squares to make a total of sixteen half
squares. These should measure 2-1/2"...
