1. Start at a corner - if possible, one that includes an edge such as a house, curb, sidewalk or other fixed edge. Lay one run of brick from the corner along the two adjacent borders. Set the brick on the sand. Don’t press or hammer them into place. They should fit snugly, with about 1/16" - 1/8" gap between each brick. As you work, be sure to work from the laid brick, not the sand. If you disturb the virgin sand, re-level it with a broom or trowel before laying more brick.
2. Continue to lay the brick in your pattern, working from your starting corner to the unanchored edge. With the original perimeter brick as a reference, put a string line across the front of your laying edge (every 2 to 3 feet) to maintain alignment. If the pattern wanders somewhat, a trowel, screwdriver, or wide-blade putty knife can be used to make small adjustments. Don’t be concerned with small gaps between the paving brick - you’ll fill them with sand.
3. Be sure to check the level and alignment of the brickwork frequently during installation.
4. Once all the full bricks have been installed up to the final, unanchored edge, cut or saw the remaining brick to complete the bond pattern - but insure that the final edge bricks are no smaller than two inches in width.
5. Anchor the final border.
