Photoshop :: Making Quill Strokes

I'm not sure if the title describes what I want to do, but here it is:

I'm wondering if there's a tool that makes strokes that look like quill strokes. Something that draws lines (not necessarily straight) that start thick on one end (and preferably round) and then tapers off as it gets to the other end.

Here's an example of what I mean. I did this manually, and I'm just wondering if there's a tool that can make strokes like this automatically.
