I just found this product at Home Depot. I made a 30x15 inch backsplash over my cook top and it's fantastic. 45 minutes of work, $20 for each 18x24 panel. Cheap, easy and impactful!
DIY tulle garland. Would be cute for wedding decorations and cheep
Use rope lights behind slightly lowered molding for movie lighting. A friend has a projector screen made of cheap white fabric and plywood boards, too. DIY at its best!
FIVE MINUTES. These pendant lights screw into existing recessed lighting fixtures and can take just a few minutes to install. Huge bang for your buck!
Large bar marquee bar sign. I don't know that this would be possible for a wedding, but I would love it!
