i found "mrs. stewart's concentrated liquid bluing" at the grocery today, $2.49 for 8 oz. since you only need a few drops, i think i have a lifetime supply! my bras have only been line-dried (cause i'm too cheap to use the clothes dryer!), and they're sort of gray-ish. i figure the $2.49 is a lot cheaper than 25 bucks for a new bra!
