Holy Brushes!

Go to http://www.youthedesigner.com/category/free-vector-art/. Download the brush(es) of choice. Open up photoshop. Go to WINDOW> BRUSHES. At the brushes tab at the top, click the arrow pointing right. Go to LOAD BRUSHES. And then, by all means, load your newly downloaded brushes. Hopefully this is clear, if not post a question in the comments.
