Decorative Bricks - Knowledgebase Question

I am wanting to build a flower box using the decorative bricks. I heard that you need to put the weed barrier down then sand under the brick. Is this true and how much sand is needed?

You can place a weed barrier down to keep weeds from sprouting beneath the bricks, but what you really need is a good base of sand on which to level the bricks. It doesn't need to be a very thick layer of sand - two or three inches at most.
