Draw a Piece of Poster Instead of a Wall to Check Colors and Finishes
Painting a small colored square on a wall is a good way to test potential wall coloring, but you will only be able to see how it looks on that particular section of the wall in a given lighting situation. To see how it will look anywhere in the room, draw a piece of the poster and move it around.
This idea from Food 52 is very clever. This not only allows you to see how color and finish looks in every corner of the room, but it also saves you the hassle of going back and hiding colors that were out of cut. You can also test multiple samples at once and move them from room to room as needed, making sure you pick the perfect shade for every wall in your home.
