I built a fire pit in my backyard last summer and it is working fine, but as of now it is just a hole in the ground and I was wanting to dress it up a little bit. What would you guys recommend I do? I was thinking about lining the walls with fire brick because now they are just bare dirt. I think this would just make it look a little nicer and more "finished". Any other suggestions how I could finish it off other than using fire brick? Thanks for any help.
