Here is how to make a watermark brush.
First you make your design using black. Whether you just want words or a picture. If you want different shades in the brush use different opacity of black. Make sure you make it big enough. This one I made 389pxs you can always make the brush smaller when using it.
Go up to edit and define brush preset. 
Next you name your brush.
Edit your photos, then pick your brush {it will be at the very bottom}. Size the brush to your liking {shortcut is {} they make the brush smaller and bigger}. I sized this to 300px and 50% opacity with a white brush.

Right now Pure Photoshop Actions has a freebie action set for resizing, sharpening and watermarking. Make sure you grab it quickly before it is gone. I used it on this photo for Sew Sweet by Kayla. For their watermark action I ran the horizontal bar. I wrote out the naptimemomtog.com in black. Then I raterized the text layer and created a clipping mask. It made it look see thru. I think I like it. What do you think? I used Pure Photoshops Hazy Baby & Sunshine Baby on it. I just won a set of actions from them. Love them!

Such a cute face! I love the photo. Nice tip.
Thank you!
Cool tutorial. Now I really need photoshop. I was thinking of photoshop elements because it is cheaper. Wondering if photoshop is worth the extra $.
Thank you!I started off using Elements. It worked really well. There are some things that are easier in CS5, but elements is a great place to start.
What a great post! Thanks so much for such a helpful tip.
Thank you Faith and your welcome.

This will help me if I ever do.
Thank you Becky. You should.
Have you also played with the fill of the brush or adding a drop shadow? I have an action now that does it all for me.
