I have lots of sketches in my sketchbook... What? Scans? Ahyeah- No... Well you'll just have to take my word for it then, wont you... :¬P In the meantime, have a little digital-after-work-something...
I found this web page ( http://lostandtaken.com/ ) a great place for textures and paper in high res. And now, finally, I feel I can REALLY sketch in PS... somehow the illusion of paper under my brush is working much better for me.
