Sunflower Nathan M. Sunflower Do you think you can build sunflower? I used pattern blocks to build sunflower. You start with 6 red rhombuses B's, 1 white hexagon, 2 green triangles, 2 blue rhombuses, 1 black and 1 red trapezoid, and 1 brown square. You start with the hexagon for the head. Then you take 6 red rhombus B's and put them on the corners of the hexagon. Then take 1 triangle and put it on the flat part of the hexagon. Then take the other triangle and put under the other triangle. Then take a trapezoid and put it on the long flat side facing up. Then take the square and put it under the trapezoid. Then take the 2 rhombus and put them next to the trapezoid long ways with the corners touching. Last take the other trapezoid and put it under the square.
