I’ve been playing around with making vector brushes. They are way harder than photoshop brushes! This set includes the whole shebang, even for inkscape. You get: free vectors, illustrator brushes, inkscape brushes, photoshop/gimp brushes, custom shapes and PNG. There’s also small text file with instructions for illustrator and inkscape.
At some point I’m going to post a full tutorial on using vector brushes in inkscape. It’s pretty intuitive with illustrator but took me a little while to figure it out. I was excited to figure it out though!!
