I'm sure most of you are tired of answering the questions for cobblewood floors, but I do need some help, please. We are interested in putting this type of floor in our entryway and our kitchen. As for the wood, does anyone have a good idea as to where to find old wood? If not, what would be the best type of hard wood to use? I also need the amounts for the grout mixture? Any help on this is much appreciated.
