Now we'll start to piece the block! Use a 1/4" seam now
and throughout the block making. Sew a Color2 Half Square triangle to
one side of a Color 3 square. Next sew a Color 4 Half Square Triangle
to the opposite side of the Color 3 square. Press seams towards
triangles. Now sew another Color 4 Half Square Triangle to the lower
left edge, and another to the upper right edge. Press seams towards
the triangles again. Make four units like this. These should measure
3-1/2"...on to Page 2!
