This tip was one of those aha! inspirations for me. Ever need a straight edge to measure and cut a large piece of fabric, cardboard, or paper? Forget cheap yardsticks (you’ll only slice slivers of wood off when cutting) or expensive T-squares (that for some reason are never really square) or fancy metal rulers (that usually aren’t long enough).
Pick yourself up a drywall T-square. They’re four feet long, sturdy, and only about $12 at your local hardware store. Now I use it for cutting all large materials like fabric, poster board, or cardboard. And the next time I cut drywall, it will come in especially handy.
