my current ones are 10.5" tall, I have oak ovals on the front of them for the beer labels. I always liked the Leinies canoe paddle handles, and a mash paddle would be similar in style but more homebrewer-ish
You should take custom orders. Then the price might not be such a big concern because people will be willing to pay more if it is custom. Like me for example. I'm a firefighter, anything firefighter related would interest me. Like a hydrant or a length of hose with a nozzle. Not sure how hard something like that would be though.
