In my country home, I keep my antique breadboards at hand by hanging them up on my wall and storing them in the wooden box designed to hold my collection - this way they add country flair to my kitchen when they aren't in use (and I do actually use them). I use them as centerpieces on the dining table, and for serving cheese and crackers when entertaining guests, among other things. I love the look of the old wood so much - I use them whenever I can!
In her book, "Country On a Shoestring," Judy Condon suggests using antique breadboards on your countertops if your countertops aren't "country" enough for you, yet you can't afford to replace them -- and she adds that antique breadboards have a richer patina than new wood (butcherblock) does and give a better country appeal (p.11). And MUCH cheaper too!
