Don't like that tea?

If you buy tea or coffee and don't care for it, use it to dye fabric. Even herbal teas can tint white cotton - good for scarves, light curtains, etc. Just make it up as if you were going to drink it, then put the material into it while it's still hot. Let it set for 30 minutes or so and rinse in cool water. Set the dye with salt and always wash in cold water.
