Find 2 inch strips of background and two different oranges.
You will need half square triangles in both of the oranges. Layer the orange right sides together with the background and use the easy angle ruler to cut 2 HST units from each orange.
In addition the these 4 HST units you will also need 4 3.5 by 2 inch rectangles in background as well as 2 two inch squares in each orange.
Sew the HST units together, trim the dog ears, and press toward the dark.
Next, sew a HST onto the top of each orange square. Mix up both oranges so that each subunit has both shades. Press away from the diagonal seam and sew these pieces to the background rectangles so that the background fabrics face one another in the middle.
Take these four finished subunits and arrange them so the orange squares form a four patch in the center of the block with alternating shades.
Here is your sampler block ready to be framed out by star points.
Adding the star points will bring your block up to its final size of 12.5 inches unfinished.
