This is one of those blocks that would be great for using up extra HST block. Bonus triangles, binding triangles. There seem to be so many leftover triangles hanging around.
If you don't have a basket of HST blocks hanging around, you can make your own in two sizes. Start with 3.5 inch strips of green and background and 2 inch strips in a contrasting color and background. I chose blue because I just couldn't find a green that I liked.
Place the 3.5 inch strips right sides together and use the easy angle ruler to cut 2 units. If you don't have 3.5 inch strips, you can also cut two squares 3 7/8 inches and cut them in half. For just two blocks it is just as easy to do it this way.
Next place the 2 inch strips right sides together and use the easy angle ruler to cut 4 units. You will also need 4 squares on background fabric, 2 inches each.
Sew all the HST units together, remove dog ears and press to the dark. The small squares will be combined with the plain background fabric to make two adorable little four patches with the dark corners meeting in the middle. Sew and press the four patches.
Next, put these four patches together with the larger HST blocks already sewn. Sew these together as a four patch with the seams facing toward the green to reduce bulk.
Easy as can be, right? Imagine a sea of scrappy little blocks together with a unifying color for the larger pieces. Great stash busting scrap quilt.
