You probably just finished your spring cleaning and threw away a bunch of old stuff you had up on the walls thinking the weather would warm up and it was time for a change. Now you have bare walls and are looking for a way to fill them, which means you need to head to Burnet Art Gallery tonight for Art 4 Shelter. More than 1000 original pieces from emerging and established artists will be on sale starting at $30 for 5″ x 7″  works ranging up to $150 for  8″ x 10″ works, and new stuff will be added throughout the evening as pieces come flying off the walls. The best part is the night serves as a benefit for Simpson Housing Service to aid the homeless. There’s no better excuse to pickup some new artwork. A preview event starts at 6 p.m. so you can scope out your favorites, and the sale begins at 7 p.m. Free. —Eric D. Johnson
