I made the block again, this time for my guild challenge, using the chambray print as background and bright prints for contrast. I Googled Mary's triangles and shaded four patches ( name of the four outside blocks) and found several methods of sewing the corner red square on a chambray rectangle and making an asymetrical four patch, which is layered with the dark blue print to make HST. I took the method one step further by strip piecing the red and chambray, cutting 2.5 inch subcuts and then making the four-patches. I didn't bookmark my references, sorry, but its worth searching out the method. Now I'm not afraid of those shaded four-patches anymore and can see some real possibilities in them. Thanks Pixie, for choosing this one.
