Frugal art

Someone looking at the pictures from the party pointed out that one of our paintings is a Mondrian. I guess it is, although I didn't know who he was. (For further education, go here.) This painting was one my recent projects. I wanted something large and colorful for our single largeish wall. After much searching, I realized I would need to make something because I wasn't going to be able to afford anything I really liked. I researched art from the 50s and 60s (thank you, Wikipedia) and settled on a blocky geometric design using the paint I had already purchased for the furniture.

The implementation turned out to be the easy part: I purchased a large canvas and gesso'd it, then laid it on the floor and used pieces of string laid on the canvas to visualize the divisions. (That was the cat's favorite part.) Then I replaced the string with masking tape and painted the divisions. When I removed the tape, here's what I got:
Total cost: $35 (for 1 canvas, 1 can of gesso, and a roll of masking tape)
Total time: about 3 hours
Satisfaction: High
