Thank you. It's my favorite sketch, actually. The info on how I made it can be found here: http://www.innographx.com/forum/viewtopic.php?t=606 . Lots of layer blending went into it as well, but the key ingredient is "threads" from Paint Alchemy. I think later in the thread someone posted where/how to get this same effect for PC/Windows with a different plug-in, and if not Paint Alchemy is coming out with a Windows version.
