it wouldn't be that hard to duplicate the pattern. here's how:
create or trace a hexagon that's the finished size you want.
find the exact center of all the flat sides.
starting at the exact centers of each side, draw a line right across to the center of the opposite side. do this with all the sides. you end up with six wedges.
erase every other line, changing six slices into three slices. you should have three fat wedges.
trace or cut apart and add seam allowances. if you plan to english paper piece, you may want to leave more around the outside edge.
baste the outside edges to the paper and continue as usual with paper, or continue sewing to the next unit without paper.
i can see why you're interested. this is very nice.
