I like Susan (
iowa2308) she shows mostly projects she's made, but if you request a tutorial she'll be more than happy to show you how. This links you to a paper caddy tutorial of hers.
Her cyber-pal Jil is fun to watch too (
stampyra).
Becca is another favorite, her blog is fun to follow too.
Laura,
Follow the Paper Trail, has some good tutorials in her EARLY uploads. She now sells kits for her projects and mostly does tutorials (based on those kits) on UStream. Great ideas.
