There is the germ of a fun idea in here at Inspiration Uncorked. I understand why they are keeping things so structured, since they are open to the general public.
However, what if this were an invitation only gathering; preferably of creative types? What if the focus was less on generating a craft project and more on sparking creative ideas? It might also be interesting vehicle to experiment with various creativity techniques; once you had built up a set of “regulars”. Not sure this is a viable business idea but having a “crowdsource” or “kickstarter” for enhanced artistic inspiration could be handy.
