I found these awesome diy tea bags at the Co-op for a welcome reasonable price. They're sealed on three sides, and you simply fill them with your own blend of herbs or teas. I sometimes feel that brewing a whole pot of loose leaf tea is prohibitively onerous (at other times its precisely what I want) and so its nice to be able to go to the comfort and convenience of these little pouches.
Then you heat seal the open end. A hair iron worked wonders.
A perfect little pouch of comfort and warmth and healing energies.
