hello friend, thanks for wanting to learn more about the maker + brand. my name is jonnie and i promise it's pronounced "john-ny". i am a big fan of hot beverages--even when it is hot outside--and spend a lot of time in my head and cuddling my pup. 

I consider myself an entrepreneur with a passion for creating experiences for people like yourself through wearable & attainable art. It brings me so much joy to make, but it is the greatest honor when a product I've made becomes apart of someone else's everyday, so thank you.

My favorite pastimes include reading, tea-drinking, learning, listening, dancing, being, creating, sharing, baking, daydreaming+dreaming, pretending, writing, photo-taking, walking, exploring, shopping for supplies, staying home, stormy weather, traveling, new experiences, karaoke, and many other present progressives.
