These are some of the brushes I’ve used in my Greeting Cards and other Designs:
It appears this site has gone down and the brushes are now only available on brusheezy now which is imposing it’s own terms of service. However when I used them they were free for use as long as you didn’t resell or post them on other sites. It’s also possible some are on Hawksmont’s Deviantart account.
