"Screeding" the sand layer . . .

A screed is a board used to level the layer of sand so that the pavers will be square, level and at the right depth. A tricky process since we had to measure from the top down and the "top" didn't exist yet. This involved string, levels, tape measure, a Sharpie, lumber, a saw, hammer, nails, a brief appearance by a clear acrylic quilting ruler, duct tape, and assorted measurements (depth of gravel, depth of sand, thickness of pavers, length and width of the patio, and calculation of drainage slope per foot). Luckily one of us is very good at geometry and math.
