I choose to build a chess set because it's a kind of a gift I would be very happy to get. I also have quite a large amount of white and green 2x4 bricks for the board. (TBB's "theme colors" are white and green, I guess..? Their webpage is colored like this, so...)
Figures were the trickiest part because I don't have that much appropriate pieces in green. So I added some secondary colors like gold and transparent and it instantly became easier.
The uploader wouldn't let me upload more photos here for some reason... So more pictures are on brickshelf.
I hope you all like it! And happy birthday to The Brothers Brick! Currently the best LEGO blog out there.
