I've been meaning to do this for a while. I've gotten all my patterns uploaded as pdf's, and created a page where you can download them all. See the "My Tatting Patterns" tab at the top of the page.
"Angels in the Snow" will still be sold by e-mail. As I learn my way around the pdf hosting site, I might be able to figure out a way to make a file accessible only after a payment has been made; or I might have to be a business user to do that. For now, e-mail is still the easiest way to do it.
Everything else is free, so far.
Update: I fixed it so the files are publicly shared, so now you can actually see the patterns! Thanks, Ladytats, for pointing this out.
