I think the second class. I would yearn to take the first one too but I think the second one might give you a better grounding into technique and things. It might open your eyes into other things besides feathers. I wonder if, after you take that class, that you could get a book on feathers and give it a try yourself? OR maybe take the feathers class next year!!! I wish I was having to pick between these two classes!!!
No matter which one you pick, I hope you have a great time and learn a TON!!!
