Need craft ideas

Does anyone make any sort of crafts utilizing golf stuff? We have a craft consignment store in this area and they have asked their crafters to make things which would appeal to golfers. I seem to recall seeing a birdhouse somewhere that incorporated golf balls and tees, but I can't remember the specifics. I also seem to recall some "critters" made out of golf balls but again, I don't remember where I saw them or even what they were. The store is sponsoring my bowling team this year and I'd really like to give them some ideas.
