@xoxos - The brush is one I made from one or two others that I made while working on another free map. Open the brush dialog box thingy and mess around with the settings on a basic one (chalk or whatnot) and then mess around some more with different possibilities for the dual brush, set it to wet blending (or whatsit called) and then make sure to save the variant when you get something you like. The spacing, scatter, and angle were the things I messed with the most. Actually, I think the dual brush was a tree or something like that, haha!
