Kitty, I did watch her video (she's the designer of the tool), plus another one from someone who works for a quilt shop. The only problem is, I can't find a video of someone actually sewing the block together. They both demonstrate with step-outs (pre-sewn pieces) which is helpful, but I'd love to see somebody using it to cut and sew the blocks.
Maybe if I figure it out, I should make that video!
