Start by cutting the Color 1 2-1/2" x 10" strip
into four 2-1/2" squares...
Then cut the Color 1 2-7/8" x 11-1/2" strip into
four 2-7/8" squares. Stack these squares and cut them once on
the diagonal to make eight half square triangles...
Next cut the Color 2 2-1/2" x 12-1/2" strip into
five 2-1/2" squares...
Now cut the Color 3 2-1/2" x 20" strip into eight
2-1/2" squares...
Cut the Color 3 2-7/8" x 11-1/2" strip into four
2-7/8" squares. Stack these squares and cut them once on the
diagonal to make eight half square triangles...
Using a scant 1/4" seam, sew the Color 1 and Color 3
half square triangles right sides together in pairs. Press seams to
darker side. Trim these to measure 2-1/2" if needed. Make
eight units like this...on to Page 2!
