I agree that the quilt pattern is very dynamic! Love it! I also agree that there's probably no easy way to piece the first block. i would go with paper piecing, but use a strip method. Print off all your foundation papers. Cut the main triangles and glue stick them into place. Then take a strip of fabric the appropriate width for the side triangles and lay the large triangles & papers along the whole strip and pin well, then just sew the entire strip. You will have to experiment a bit to get the proper spacing. Use a long stitch length till you get it figured out.
Last Christmas I made a quilt will 16 stars with odd shaped points that had to be paper pieced. I used this method (which I thought I invented) and it went pretty quickly. Then I saw the book: "Quick-Strip Paper Piecing", so maybe I didn't invent it after all LOL.
