2) 2 acrylic paint colors;
3) Fat paint brushes (I used the sponge ones);
4) Painters tape;
5) Hanging mechanism (I used pushpins because the canvas was so light).
1) Paint your white canvas with a base color. This will be the color that gets "blocked" by the tape and ends up being the accent color as opposed to the dominant color. I would recommend that you make the blocked base color lighter than your top coat, otherwise you will be spending a ton of time painting and repainting the top coat to cover a dark bottom. You can also use spray paint if you have a big canvas--I did that for another project where I did an acrylic base that was blue and then spray painted white over it.
Here is is all painted:
I had to do a lot of coats of spray paint.
