pattern to make re-usable swiffer rags!

I looooove my swiffer sweeper and my swiffer wetjet.
But I don't love the price of the replacement rags. I've taken to using microfiber cloths because they stick well to the little Velcro pieces on the swiffers and are machine washable.

But I came across this pattern to make crochet swiffer rags! If you can crochet you may want to check this out!

Thanks to tipnut for the information!
