I picked up this mid-century abstract oil painting at the flea market a while back. I liked it enough but it definitely wasn't love. I bought it for about $20, so I figured I could make something hang-worthy out of it.
When I got it home, I knew it had to be changed. The colors looked so, so drab with my mustard rug and ivory sofa. So using just a couple tubes of oil paints, I mostly went right over the top of artist's patterns and just brightened up the drab colors. So easy! And it looked like a brand new painting in just a couple minutes. :)
