getting ready for my new Ashford install and am thinking about what to do for a hearth pad. I'm thinking I'll make it myself. I'm debating whether to make it out of tile or to make it out of a piece of cut limestone. What are some of you guys making them out of? Also are you raising them up a little or leaving them right on the floor? If you're raising them how much. Any ideas are appreciated. Pics would also be helpful if you have them.
