I've been discovering more and more about art every day~
I've found that brushes and materials/textures are really important to me, I want to include interesting forms in my art even when I'm drawing something simplistic, and the best way I can manage that is with interesting brushes and textures~
I've been messing around making brushes in Sai and clip studio Paint Pro for a few days now~
I found some screentone textures to use in Sai here: [link]
And they are really helpful! I was about to set to work making a million tones for SAI (I have found SAI is what works best on a tablet PC I use for art away from my main work station) but then I found that! So helpful~

Though I like to make all of my own textures and brushes, sometimes I run into something like that and will use it as a time saver or to learn more about how to make my own. But I'll always credit the maker of them~
