Knitted vase cozies like the one I made here? Maybe.
But then I came back to this idea seen awhile ago on Style Me Pretty, done by Twig & Thistle. I think these are black, but I like how they appear a deep aubergine. I like that cheapy crappy vases suddenly look chic and unified.

What I like about this is that the clear glass makes the color appear shiny, almost lacquered. A very different look, but also pretty. Potential drawback, all of these vases would have to start out clear glass.

So! The mission for this weekend is to acquire some purple-ish spray paint, hit the goodwill and try painting inside and outside of some vases. At worst, I'm out a few bucks, a few hours, and a few glass vases. At best, I'm one step closer to tablescape heaven.
