Sean, you can get all the info you need about scrolling, by participating and asking questions here on the Village. There's other scrolling sites that have lots of info also, you just have to read their forums. As for patterns, you can find some on here as well, just check out the pattern library. All scrollsaw sites have pattern libraries, that's another good reason to check out other sites. As for a good pattern book, there's many, it all depends on what type of pattern your looking to cut. There is one good magazine that you might want to look into, it's called Scrollsaw Woodworking and Crafts. It's published about 7 times per year, and it covers a lot of scrolling subjects.
