Drying herbs and flower petals

I'm sure you've seen special systems for drying flowers and herbs.  You might wonder, "How did people historically dry herbs or flower petals without weird modern chemicals and gadgets?" 
I can't answer that question for you.  But I can tell you a nifty way to dry some plant life.

Here is what you need:
A mesh screen
A dryer (In our apartment we have a dryer stacked on a washer in a very small space.)
Whatever plant matter you want to dry.

Scatter the herbs or petals evenly on the mesh.  Lay the screen on top of the dryer.  Let it sit there for a few days.  Then check to see if your plant matter is dry.

Very easy, very simple, very non-toxic.  This idea belongs to Angelowe, which she came up with randomly one day.  It has been very helpful and effective.
