The top and side banners needed to be separated from the main interactive area where the users would draw, now to do this I had originally used just a basic line though I thought this looked out of place slightly with the other content having a drawn/sketched look about them.  This prompted me to look at the various brushes within Photoshop to see if I could produce a roughly draw line that would fit in with the theme I was attempting to create.  I tried many different styles but chose to use the brush named 'hard pastel on canvas'  thought this gave the best effect and look.

 Used to separate main interactive area.

I thought the brush worked well so I decided to use this to produce the buttons for the image bank sections.  Users will use the buttons to navigate to the image bank of drawings they wish to view.
