http://resources.deviantart.com/applications/psbrushes/ http://prettybrush.cjb.net That's where most of mine are from. To install, unzip them (if they're in a zip file) into your brushes folder, it'll be Adobe > Photoshop > Presets > Brushes, then when you open Photoshop, select the paintbrush tool and click the little thing at the top that lets you chose what brush you want to use, and then click the little arrow, go down to "load brushes", and click the ones you've just downloaded. I've found that sometimes you don't need to load the brushes, though....
Thank you so much for the help! I would rep you but i dont have 100 post so i will cred you instead. ^_^
i dont know how everyone else does it but when i download mine i save them then just go in photoshop and go to File>Open then click on the brushes i dont put them in the brushes folder and it works just as good
