With the plethora of free resources for Photoshop on the internet, it seems ridiculous to actually pay for them, right? But as a wise goblin once said, "Time is money, friend," and hunting the internet for maybe finding something that will make your project easier seems like time better spent elsewhere...like actually working on the project in question.
So, I'm going to save you some internet footwork, and tell you to spend a modicum of cash for Frenden's brushes. I admit, I was hesitant...but holy crap. No regrets. None.
Check out Frenden's website (or watch his videos on the YouTubes, then go to Frenden's shop, and if you Tumble, tag your work with "frenden brushes" or "frenden."
Show your stuff off...which I will do myself at some point. >.>
