Well, it looks like you have an octagon (8 sides) in the center. Then the sides (left, right, top and bottom) are straight pieces all of same colour. The corner triangles are three colours--first a strip the same as the sides, then a strip of black and then a strip of the figured. For that part, I would sew the strips together and then cut the 45 degree pieces. You would be working with bias but it shouldn't be that difficult. Very pretty pattern and the quilting really changes the look of the blocks.
