Here's an easy tip for you. This comes, again, from the America's Test Kitchen DVDs that I've been watching. I made this "sling" with parchment paper:
The bread snuggles nicely in the sling, and rises well.
And look at how clean the pan is, where the sling was. If I was really fancy-shmancy, I'd put another sling long-ways. Oh well :) This makes for a clean pan, and less waste on your bread loaf.
The ATK folks also used a sling when they made delicate cakes in 8x8 pans. And you don't have to use parchment paper; they also used aluminum foil. However, I strongly recommend having parchment paper in your kitchen; it's an indispensable tool and keeps all kinds of pans tidy and easier to clean.
