Post-It Note Calendar
Source: Martha Stewart Living, January 2011
Make a monthly calendar that's as changeable as your schedule. Instead of crossing out plans as dates shift, just move the notes and stack them up on busy days.
Start with a 26 1/2-inch square sheet of Masonite fiberboard. Spray-paint it white, and let dry.
Then use tape (we suggest easy-to-reposition washi tape) to create a seven-by-seven grid of three-inch squares.
