I've loved the themes this year, but I can see how for some they may be frustrating. I think that a theme like "1877" although brilliant for some, leaves less scope for interpretation for those who do not make historical replicas. We all work differently, but perhaps two different themes would be an idea? One structured and one less structured?
I enjoyed the themes this year a lot. I've always focused the shape of my corsets in terms of large hipspring, small waist, and this gave me a chance to explore other silhouettes, as well as different top and bottom edges

It all depends how you work I suppose - no matter how this is run, someone will be unhappy with it.
