For those of you who are unfamiliar with the name David Gell, he is someone you definitely will want to be aware of. David is forever creating nifty brushes, Painter scripts, Mac utilities and more. He has been doing this for years and his web site is a veritable treasure trove.
David's latest gift to the Painter community is a series of pages showing small, clickable thumbnails of all the Paper textures which are included with the "Extra Content" from Painter 12. Since most of this content is also usable in Painter X3, you will want to check this out.
In addition, David has also added a gallery which contains the Default Painter X3 Paper textures. These thumbnails make it very easy to check out the papers and decide which one to use for your work.
Thanks again David.
