Hi--
The other day I was in a Pottery Barn (chain), and they had on sale (at half price) a huge tea ball-- about the size of a large grapefruit... Stainless steel, perforated ball, with chain and hook. It is laughably large, and while the English label on the box says "large tea ball," the French label says "boule à thé décorative," which is probably more accurate. Anyhow, it's a hoot, and at half price, only $7.49-- so if you're into stuff like this, look for it.
Disclaimer: Even though I know what a tea ball looks like, I brew my tea loose ;)
