There are lots of thing you can compost that most don't think about.
one is teabags!
What about the string you ask?
For the most part, you can vermicompost entire teabags (tag, string, and bag) with the exception of the staple. Choose a tea bag with this in mind. The new tea bags that are triangle are no good, because they are almost a silk like bag. not good for composting.Celestial Seasonings is a good choice, as they refrain from using staples in their teabags; or I guess you can opt for a tag less teabag.
