If you're looking for a little kickstart to your creativity, I do recommend taking a class with Stephanie Lee. I'm just finishing up on online class, Homesteader's Metalsmithing. I've really enjoyed it. Sometimes in classes there is more "down time" than I would prefer even with the best of instructors. In this format, I can do what I want, when I want, which suits my personality (and limted time) quite well. Another plus to this class was that most of the material was brand new to me, so I feel it was time well spent, for sure.
I had heard of some of the techniques covered, but never tried them. Taking this class was one way to give myself "permission" to purchase the supplies I need to try new techniques, and to devote precious minutes to experimentation and making things that won't necessarily end up for sale. This class has inspired me to make sure I set aside the time to engage in creative play and artistic exploration.
