I LOVE scribbles ... but being who I am I always have a hard time doing them (must be my engineering brain). I've almost got it down digitally, but I've been also working on doing them with paint. I really liked how these came out. These scribbles come with 2 ABR files: one is 2500px and the other is up to 3600px. I've also included the PNG files.
These brushes are ok for commercial use along with S4H, S4O, and Personal Use friendly. You may also use them for creating freebies as long as you modify them in some way.
No credit required for the use of these items, but it's definitely appreciated.
