Repeat this process for all corners you encounter.4.
Place the deadline of the board into a 90-degree corner of the patio slab.

Use nails measuring 4 inches long, and leave an inch sticking out to make removal and deconstruction of the form easier.
3. Butt a second 2-by-4 against the cornered end of the previous board, along the adjacent edge of the patio and against the row of wooden stakes on this side. Ensure the corner measures exactly 90-degrees and adjust as necessary with a carpenter's square. Level the top edges of the two adjacent boards and drive two nails through the side of the first board into the end of the second board. Engage in not fix stakes directly into the corners of the excavation aim, and avail a length of record to deal in the stakes in a straight limit against the borderline of the excavated sphere.2. Fix a 2-by-4 board into habitat against the wooden stakes. Decrease the board down to bigness, provided required, with a table proverb.
