The easiest thing to do with the octagon blocks is just to add triangles to four opposing corners, that will make a square for a straight layout. If all the triangles are the same color, they will form a little square of color. If you use two different colors, you get hourglass shapes.
This is one of my less-successful tops for a number of reasons and it never got finished. But I used thrift store fabrics and learned a new technique. I didn't have as much of the OBW fabric as I would have liked and so had to extend what fabric I had...
