oh for like. fabric-like rough textures i kinda use this brush i downloaded on their website (they have a whole list of unique and different brushes used by other great artists that u could download for free, it's amazing), its called the halftone brush set?
and in there, theres a specific brush called "newspaper" and that's what i use to give that sort of rough texture!!
other than that, there isn't really anything else i do for texture that's unique to autodesk sketchbook? so yeah
