I follow several that have already been listed, but here are a few I love that I didn't see listed above:
Stamp & Scrap with Frenchie
On A Stampage...
3 Monkeys throwing around some....PAPER!!!
As for following a blog, there are often several options. I have my own blog set to allow people to subscribe by email or they can click the "join this site" button and join through Google Friend Connect. I like using the Google feature because I can see new blog posts from my favorites in one place, but I also subscribe to some blogs via email, and I have several people who subscribe to my blog via email rather than through a reader. There are usually lots of options, so use whatever is easiest for you!
