How do you do that, if you make it in the mug? Please don't tell me you re-use old bags!
It isn't rocket science. I put the tea bag in the mug pour on boiling water, add a drop of milk, stir it round then put it into the second mug and repeat the process, then put the bag in the compost bin. My husband and I only have two mugs of tea per day, two cups of instant coffee, and the rest of the time drink water. My husband has to drink plenty of water due to one of his health problems.
I believe one of our sons-in-law likes to reuse old tea bags, not something I wouldn't do.
