I am getting everything all ready to finish the hearth pad and ledge stone on the wall this weekend for my upcoming stove installation! So I was initially going to use some type of trim( chair rail) or other form of wood, also considered that steel tile edging however is not large enough to accommodate the stone. Then I just figured I would get some 6" travertine to match the stone! I cannot find anything to match the stone and 6" peices all The way down the 40" space may look odd! The wood is a last resort, so I was going to go to the stone place( about an hour drive) and see of I can find something that is one peice that will cover the edge up in one length! If anyone else has encounter this problem or has a crafty idea as to what to conceal the edge with that would be awesome to hear your input!
