That's an amazing idea. I over-Swiffer, I think. (But it's SOO worth it!)
If I could crochet, I would make like 10 of those.
The basic pattern is actually knitted. I crocheted the "handles" because that was what kbauer did, and it is fast. But there is no reason you couldn't do them in some garter stich, just make sure you have button holes!
