Tool School and it's run by Jennifer Gallacher. It's supposed to teach you tons of different ideas for using your crafting tools. I had been waiting for some reviews to come out and people are loving this class. I also read that she has tips for using a paper crimper, which I have and haven't used yet, so I'm really looking forward to doing this workshop.
I'll keep you guys posted on what I think about the class, but I wanted to share in case any of you might be looking for an inexpensive and helpful workshop. The class includes a 37 page PDF with 100 ways to use your tools, plus she has 120 minutes of video and plenty of example layouts using some of the methods she describes in the PDF. And it's only $12. Check it out!
