Dwyn authored a post a while back on podcasts. I also love my podcasts. I've started making lampwork beads again, and I'm enjoying listening to both audio books, and a regular selection of podcasts on a variety of subjects while melting glass.
I've compiled a list of interesting craft related blogs for you. Check out Itunes for many, many more on your favourite subjects.
