Wildyard, I'm not Karen, but the way to get the corners for the octagons is to take your strips you cut your pieces for the octagon, cut it in squares, then take a stack of 4 so you have 2 stacks of the same design (you layered your fabric to get the repeats for the octagons, so you have it for your squares as well). Then take the 2 stacks of 4 layers,(make sure the fabric is facing the same way or you may get the same triangles, and you want them to be different) and cut one from top left to bottom right and the other from top right to bottom left. This way you will get 4 sets of triangles, and they will all be different, and you can place them on your design wall between the blocks where they look the best. When you sew them together, take one octagon, and the 4 triangles around it (they will not all be from the same "stack") sew it into your block, put it back on your design wall and take the next one down. Once you get all your triangles sewn to your octagons you can start sewing your rows together.
