Just to update, I took Dave's Zoom class on Tuesday. It was really amazing! He's such a good teach and so personable. The day just flew by. His paper piecing with vellum technique is really good. I'm working on the blocks now and will update with pics when I have more of them done.
I'd highly recommend his Zoom classes. It was really nice not to have to pack everything up and get on the road early in the morning for the class. I also didn't get stressed and worry about forgetting anything. If I had machine problems, I could just use another one! Made for a very pleasant experience.
