First I added a texture using this tutorial ~ http://coffeeteaphotography.blogspot.com/2008/11/coffeeshop-texture-tutorial.html
I even found the free textures on her site. I used one of the Barnyard Textures on this photo.
Then I rounded the corners using this tutorial ~ http://coffeeteaphotography.blogspot.com/2008/08/coffeeshop-rounded-corners-free.html
Lastly I made the watermark using this tutorial ~ http://coffeeteaphotography.blogspot.com/2009/09/coffeeshop-editing-101-making-your-own.html
Now I did know how to do this but I wanted to find out how to make it a brush.
Here is the original photo. (on a side note my kids, when they want to, love the camera)
And the after.
Not bad if I do say so myself. I can see doing this on more pictures. It was time consuming only because it was my first time but with practice it could go fast. I did save it as a png but for some reason it didn't work. there is a way to get it so the corners aren't white. I will play more tomorrow.
Hope you had a great day.
