Recently I was doing a few designs and I wanted to draw a design uses brushes that mimic painting and I found some in the brush library. After using them I realized since it didn't create those brushes it wasn't fully my design. Can the brushes be used for commercial use or is that not allowed? I should have created my own brushes.
So if you are doing a painting using a brush that you bought in a shop, is the painting not your own work?
Or is it a requirement that you go and shoot a badger so that you can make your own brush?
Kolinsky Weasles are what you're after. http://en.wikipedia.org/wiki/Kolinsky_sable-hair_brush
Back in my college days, I was told that they raise/catch these critters and snip off just the hair from the tip of their tail. Easy enough, right? Except that once you cut the hair, it grows back differently (you know, with a squared off end since you cut off the tapered end...) so each weasle can only be used once for the premium quality brushes, hence their incredible price tags. http://www.amazon.com/Series-Kolinsky-Brush-Winsor-Newton/dp/B0049B38I 2
Sorry, I was wondering about this because I was going to use patterns in my design and there are issues that the patterns cannot be used for commercial use. Thank you guys for answering my questions.
