Kari, that is very true about the tea balls! I suggest them to new-to-loose-leaf-tea drinkers because they are just so much simpler hehe. Ideally, you'd leave the tea leaves to float loose in the brew and either strain out or even drink around them, but I find the tea balls are a great time saver. As long as you don't overfill, they have room to expand; I usually suggest half full, though some teas unfurl to a much larger size than others (for example, white teas need much more room than say a crushed darjeeling).
Alicat, no problem! If you have any questions feel free to ask me, I do loves me my tea ^^
