I don't understand why you can't teach that class.
You have such a lot of valuable wisdom to share. The feds are already discussing how to apply exemptions to this law. Not should they, but how to.
Many raw materials, such as wool, cotton, etc. will be expempted. If you help even a handful of families learn to sell diapers, or stuffed toys, or clothing online, you will be doing a great service to your country.
