Ohh, yes. I've had plenty of premise bunnies that may or may not grow into a plot bunny. Sometimes it'll be an image in my head of some locale or someone or an idea, but that's it and that's not enough to hang my hat on for any sort of story.

I did have a premise bunny recently in the form of a food item prompt and the way I worked it into a proper plot bunny was actually by channeling Project Runway critiques and trying to figure out how I could use said food in a story with actual plot. And it worked! I am writing that fic right now. :D
