Any secrets to flagstone laid in sand?
There are two keys to laying flagstone. First, choose the largest stone you can move. Thickness should be an inch and a quarter to three inches (thinner may break, thicker is too difficult to move and is a waste of money). Secondly, prep carefully prior to installation. Insure that your sand is contained and cannot be washed from under the stone; then wet and screed the sand several times prior to dropping your stones in place.
