Even on rough carpentry projects, such as laying out a wall or partition with a carpenter's square, sharpen your pencil after every six marks. Using a blunt pencil could add as much as an inch to the overall dimensions over about 20 feet. This can throw the entire structure out of whack and make it difficult to fit wallboard, sheathing and other modular materials.
If you want an instant lawn, sod’s the only way to go. First, prepare your soil with lime and fertilizer, just as you would for a seeded lawn. Lay the strips of sod in a staggered pattern so that the joints overlap. Make sure the seams are tight so that when the roots knit, the seams will be invisible. Make sure you roll it all out in one day. Even overnight, rolled sod will burn yellow. Keep your new lawn well watered for several weeks until new roots have penetrated the soil.
