You'd think this would be an easy task. You'd be wrong.
I searched at tons of places - World Market, Ashley, Target, Z Gallerie, Macy's, TJ Maxx, Pier 1, Anthropologie - but no one had anything that would work. Everything was either too close to the floor, too narrow or far too expensive. But in a last effort at my second HomeGoods, I found these:
Two tables wide and tall enough for the vents, with a cool shape, for only $39.99 each. But oh - one was black and one was white, and no ma'am, everything we have is on the floor and going in the back to look for another table just like one of these won't do any good. Hmph. Hello, paint.
