Thishas to be one of the neatest ideas that I ever saw. I do remember that they used barn posts but I would liketoknowagain what they ;used for the grout. I remembered that they used some type of sawdust mixed with a solvent. There is a nice coffee shop here that used the same idea using pine on edge but they varnished over it. I must say that the cobblestone look is much nicer. Any ideas when this eppisode will be aired again?
