Dry-laying bricks in a walkway

Along the side of our driveway we've always battled mud, weeds, tripping hazards and parking difficulties. It's heavily shaded by the house, so more garden wouldn't do well and we'd always be squishing things as we come and go in the car, truck, bike, stroller or wagon.

I've been collecting free bricks from Craigslist for a few months and finally had enough to make a start along the driveway and to finish off one side of the deck.

First, I removed 4.5 inches of soil below the grade. Then I added about an inch of 3/4 minus crushed rock (gravel), about an inch of sand and then set the bricks on top of the sand. Each layer received a thorough tamping, and the bricks got set into place with a rubber mallet. Once set, I swept sand into the cracks between bricks, set them again with the mallet, then swept more sand. It's been about a week or more, and it's due for another sweeping of sand. Eventually, all the sand particles will settle down.
