A couple of you (you know who you are) have asked about the writer's revision towel I showed Raine in comments over at the Chicas.
Here's the towel (click to see larger image):
It's not bath towel-size (how would you get that in your mouth?); it's 7.5" X 11.5". It actually works nicely as a dusting cloth, with or without the spit.
If you want your own or one for a friend, you can order it online here at Author Outfitters. They have lots of neat products for writers, and can even customize them for you with your images or cover art. I love their mugs, which are a great size, immaculately printed and perfect when you need a gift for a writer or editor friend.
