Wow -- as much as I am an autodidact, to learn under Michael Sull would be wonderful! I have learned so much from his (and Debra Sull's) Learning to Write Spencerian Script. The four-session online workshop and price point also appeals.
Hoping he may offer a similar online class format at a more beginner level some day. I have much more basic skill and technique to practice and acquire before launching into ornamental capitals (barely have the regular majuscules learned), flourishing, and composition. I definitely did sign up for mailing list, though.
Thanks for sharing this link!
