(Mods, feel free to move this to Customs if you think it'll go better there.)
After everyone's disappointment with the paper accessories in the 2013 Favorite Friends set, I can't help wondering if people would buy removable Sculpey accessories for their G4s.
I've also been thinking of making the other 5 Elements of Harmony (Twilight's Magic crown element is already an official item) and maybe Applejack's hat for people who don't like her CE hat but don't want to repaint it.
I feel a lot safer baking Sculpey by itself than permanently baking it onto a non-baity pony (Call me crazy, but I'm NOT putting a pony in the oven).
