Economy Quilt Block

I attempted another quilt block drawing using my "WACOM" drawing pad. This block is called "Economy". I'm not sure why it's called that, but maybe I'll try to research it at a later date.

If you want to make a block like this, then you will need to make:

4 x 5 7/8" rectangles for the outside

1 x 5 1/2" center block

1 x 6 1/4" square block , cut into fourths (purple)
