Post-it Notes are useful for much more than leaving reminders to yourself and others. Since they're available in many colors, it's possible to use them to create cartoon or pixel-style art reminiscent of old video games. The sticky matter holds the art up on a wall, easy to remove or reposition as needed. Plotting your design on graph paper, with each square representing one Post-it Note, makes reproduction of even complex designs a much simpler process.
Wipe down the project area with a duster or a soft cloth to help the Post-it Notes better adhere to the wall.
Study the image you wish to recreate on the wall. If you don't have a picture, doodle an image or abstract design on graph paper using colored pencils. Create a block-based rendition of the original art on the graph paper, coloring in each used square with an appropriate colored pencil. Each color represents one color of Post-It Note, so you will know which colors to use on the wall.
Select one corner of the graph paper design as your starting point and choose a suitable location on the wall. Place a Post-it Note matching the color of the graph paper block on the wall at the chosen location.
Place a second Post-It Note, representing an adjacent square on the graph paper, next to or above the first. Continue placing notes, working in methodical rows or columns, until the design is complete.
