The first thing you do is clear your area and prepare your canvas and your masking tape. In this instance we used ordinary cheap masking tape.
Now start masking of strips of your canvas starting from the bottom left corner traveling up the the top right corner.Now proceed to paint the entirety of the canvas in a single color with a single even coat. For our first application we chose the color Blue and I am using spray paint. You may use whatever color or type of paint you want. Once it is covered let your canvas dry for as long as your particular paint requires for it to be dry to the touch. Once your first coat is dry to the touch, start unmasking your canvas and reveal the white underneath of your tape. Once you have removed all the tape from your canvas, begin remasking your canvas in the opposite angle, starting from the bottom right corner and traveling up to the top right corner. In this instance I was able to re-use the tape and so it is blue in the photo. Proceed to paint with your second color of paint apply another coat on top of your alternatively masked canvas. The second color we chose was a bright green. Once your second coat of paint is dry to the touch, you may begin to unmask your canvas once more revealing your pattern beneath. You should be pretty excited at what is taking place here at this point. Once your tape is removed and you see the pattern you have so it is time for one final masking. Take your masking tape and mask your canvas again, this time from left to right making horizontal strips across the canvas. We went for a slightly thinner stripe this time. Again, we re-used the masking tape. The horizontal stripes are green in the photo. Once you have finished masking the canvas in this manner, proceed to apply a third coat using your third selected color. In this case we chose to use a stylish purple. Once your third coat of paint is dry to the touch, you may begin unmasking your canvas for the last time, at least with tape. You see we have three colors painted now in a pattern. Once you have removed all of the masking tap from your canvas and have revealed a sweet pattern, you will prepare for your final steps in your painting. Prepare your letters. Think of something inspiring and encouraging to display on your canvas. After all you will be hanging this somewhere right? Also once you have come up with something, make sure that you have all the letters or numbers you need. If you have trouble placing your letters you may always use a level and more tape to place your text. Just be sure to remove that tape before painting again. We also cut a heart shape from an old sticker and used it as a cute decal for this craft. Once your black has dried to the touch use your blade, and begin to carefully peel away the letters and stickers from your canvas. Your canvas should look dingy and dark except for that which you want it to say. That should POP with color in contrast.
