Here is the Pinterest project I ended up doing tonight. I love how it turned out! The colors are weird here (very yellow) because the only lighting was from a lamp. You get the idea, though.
This is the original project. I didn’t want so many colors. Our living room has brown furniture with blue accents (pillows, wall hangings, etc) so I figured different shades of blue and a few brown circles would look cool. It wasn’t hard at all – I just painted the canvas a light tan (white and brown mixed), drew on the limbs with the paint marker, and then dabbed the circles with the circular brushes. The small circles were free handed.
