I am also working on preparing a workshop for my local guild. This program will be on Summer and Winter... but as we know, that's referred to as "single-two tie". I am planning on two days to play with this weave structure.
The workshop will be geared to the four shaft loom. Most of my explorations has been on eight shafts, so it's been fun weaving samples on just four. I hope I have a few sign-up, as I think it will be an informative workshop.
