This is in reference to Board Question #20160.
My recommendation is to find someone from Ohio. We Ohians know what to do with buckeyes and our mom's will have great center piece ideas and other decorating ideas too. (It would probably be easier to ask someone than to post something here.)
On another note, quite often Ohians make necklaces out of buckeyes, especially when the Ohio State/Michigan game is on. But most of us prefer to have true Ohio buckeyes for the necklaces - for better luck.
