DIY Wall Art: Chevron is huge right now. Its also a pattern that can easily be created on a canvas. Measure, mark it off with tape and then paint in your favorite colors. Instant and inexpensive wall art to match your decor.
Paint a canvas with lots of colors--abstract. When completely dry, use painter's tape to create a design (chevron in this case). Paint over the entire canvas with white or another color paint, and remove the tape (before allowing it to dry)
Hand painted tree rings - would recommend putting all tree rings on a board (which could be painted a coordinating color to add pop to the art piece. Really neat idea for after school kids. Might just do 9 rings in a square frame!
