One lady extended hers out 6 inches to a foot so she could hang a bird feeder on it. But just make sure (the rung) is long enough to nail into it one inch from the end. If you are too close to the end, the wood can split.

You want two posts that are close to the same size so they are not real lopsided.

It's rustic if there is extra brush on it.

I'll show you how to bend that to make it into something.
