using color 1 (lt or med) squares and 2 same size background squares, construct 4 half square triangle units. They should measure 2 1/2" for 10-inch block and 3 1/2" for 15-inch block. Cut remaining larger background squares diagonally in half making 8 triangles.

 

Construct corner units by sewing background triangles to half square triangles making a large triangle. cut the large color 1 dk squares diagonally in half making 4 large triangles. Sew pieced triangles to dk triangles making a square unit as shown.

 

 

Sew the color 2 squares and background squares to form 4 rectangles.
