Ok - so that is super easy to make. You can do 2 colors, or 4 colors, or however you want.
Basically, you need a total of (8) 3.5" x 6.5" rectangles and (8) 3.5" blocks. Draw a diagonal line on the block, line it up on the rectangle, sew, trim, and iron. The tricky part is making sure you go the right direction (diagonally speaking) depending on the part of the block you're sewing.
Once you've got all 8 sewn/cut/ironed, start putting them together like the block picture. Super simple. But it's pretty awesome and not a traditional design.
