My House with Windows?
(Edit: Approx folding time if you already know how to fold it is 90mins, so it would probably need to be a 3 hr class)

Or my Atomic Detonation?
Uses crumpling and wet folding.
(Approx folding time 10-15 minutes, so the class could be 30-45 mins)

As a side note, if you want diagrams for the House with Windows I can send you a PCP/photodiagram.
