That block is much easier than it looks – it consists of rectangles (the focus fabric) and black strips on two opposing sides. So let's say your focus block is 6"x4", and then you add 1" black to either side (I'm talking finished here, not allowing for seam allowances). You'd have a 6" square. Make two of them and set them side by side, placing one fabric focus vertical and one horizontal. Since they are both squares, they should match up nicely. The rectangular focus fabric only makes it look like the blocks are different sizes. Hope that makes sense!
