Have you seen the pamphlets at Hobby Lobby in the fabric section? They have some interesting ideas in them. You can download them here. Also click here to get Hobby Lobby's weekly coupon. You might want to bookmark the link. The link doesn't change but the coupon does. This week it's 40% off one regular priced item. Last week it was 30% off Rustoleum or Krylon spray paint (no limit!)
Speaking of Krylon, their website has lots of spray paint project ideas and techniques like this one.
