Duke William of Normandy won the battle because was well prepared and had a good army. They prepared carefully for the battle. The Normans had knights on horseback who were skilful fighters.
A utility knife, metal ruler, and a hammer can be faster than trying to carefully saw an opening. Score the drywall a couple times till you are most of the way through, then just knock a hole with the hammer and break the drywall back at the score lines.
So, here are a few tips to make the job a little easier. 1  Make a Door: When cutting out a square, leave the 4th side uncut--use this as a hinge to leave the drywall flap in place. 2  Don't Cut Between Every Pair of Studs: Cut only between alternating studs cavities. I've found that I don't need to cut into every cavity. I can (usually) direct the wire blindly through the closed-up cavity into the hole in the stud.
