Lol, I actually tried that, not 4 times, but reused once and tea was all light colored and like drinking colored water basically. Tried it because didn't feel like going to store just for tea bags that I forgot on shopping trip the day before. So really didn't need anything at all besides tea bags.
Anyways, lol at 4 times. There's no way
Back in the day I have used picnic napkins for toilet paper a few times. I'm sure there's a few that has done that at one point another besides me.
