Our doormat used to be really cute. It didn't take long for it to fade into a really ugly (but still-functional) mess. I didn't want to throw it away and I also didn't want to waste money on another one that would similarly fade into yuck, so I decided to refresh it a bit. I spray painted the whole thing black, let that dry, and then used tape to mask off a zig zag pattern.
I had some leftover gold paint from the picnic table and used that to spray the zig zags. The final result is a far cry from the fabulous original, but it's way better than faded and gross. Oh, and don't be worried...I'm now officially over the gold.
