The One Project Closer Before & After series supporting Habitat for Humanity is in full gear. If you've completed a DIY project recently, send it in for a chance to win a $50 gift card! Through the entire summer, they're picking weekly winners and publishing their before and after story on OPC. At the end of summer, voting begins and the grand prize winner takes home an additional $150 gift card! To join in, submit pictures and a story to BeforeAndAfter@OneProjectCloser.com.

This is the fourth year One Project Closer has run this series to help raise support and awareness for Habitat. In addition to winning a gift card, OPC makes a $100 donation to Habitat in your honor. All together, they'll have donated more than a $1000 by the end of summer! Not too shabby. Plus, keep your eye out for the Habitat fun fact on each Before and After post to learn what Habitat is doing all over the world.

If you like home improvement projects, let OPC help you get started. $200 worth of gift cards can go a long way, especially when you combine that with a Lowe's coupon or Home Depot coupon. You've put in a lot of work, and it's time to claim some of the credit. Let OPC feature your awesome before and after AND help out a worthy cause.
