The lessons were clear, well-paced, and interesting, and Lisa is a good teacher. I only had some difficulty when dark colored yarn was used for demonstrating the more advanced stitches- even on full screen, the stitches all merged together and it was hard to tell just where the hook went or what was happening with the loops. For example, on the Wave Stitch video, the greens both appeared navy, and the light colors both appeared off-white, so it was not always easy to follow the instructions, especially with the green yarns.
