Cross cuts are cuts the go against the woodgrain. Once you've properly measured and marked your piece of wood, guide the side of the handsaw blade with the knuckle of your thumb. Start the cut by pulling your hand saw up two or three times, then push the saw blade forward at about a 45 degree angle. It is preferable to begin your cuts on the side of the wood that will show less when the project is complete.
Don’t set your thermostat at a colder setting than normal when you turn on your air conditioner. It will not cool your home any faster and could result in excessive cooling and, therefore, unnecessary expense.
