I couldn't find the kinds of textures I desired for use in my digital art, so awhile back I made my own! These are acrylic on watercolor paper, the highlights of experimentation. I scanned them in at 6000 DPI using an Epson professional scanner.
Donations for this are appreciated, and I'm also selling a "master pack" containing the full files these crops are taken from.

Thanks for checking out my hand painted textures. If you liked these crops but found they were too limited in scope, consider purchasing the "master file" version.
