I agree entirely. Not only is it better, it’s practically required that you create some sort of mess to reach the end result of creativity. Sometimes that mess is physical, sometimes that mess is just part of the process in your mind.
What’s the biggest mess you’ve made in your creative work?
The biggest mess I’ve made was throwing all my embroidery and bobbin lace “odds and ends” into a tubby while packing for a move two years ago. I’m still finding/looking for stuff.
