How far could this idea go?

I’m Jenny. I turn simple ideas into stories, characters, products, brands, businesses, and experiences, and share what happens along the way.

Stories • Creativity • Community

Creating stories, mail clubs, and creative projects that inspire curiosity, creativity, and connection.

It usually starts with an idea.

I’ve always been fascinated by the possibilities hidden inside ordinary ideas. A story can become a character. A character can become a book. A simple question can become a product, a business, or an entire experience.

I like to follow those ideas and see where they lead.

I don't collect ideas. I explore them.

What I'm Creating

Ideas are only the beginning. Here are some of the stories, products, experiences, and worlds I’ve created, and ways you can make them part of your world, too.

A Little About Jenny

Hi I'm Jenny!

I’ve always been someone who sees possibilities in ordinary things. An interesting thought, a character, a place I visit, or something I notice in everyday life can send me wondering what it might become.

I’m a creator, illustrator, storyteller, and lifelong idea explorer. Over the years, my curiosity has led me to create stories and characters, design products, build brands and businesses, make things by hand, and dream up experiences that bring an idea into the real world. Some ideas become books. Some become businesses. Some grow into entire worlds. And sometimes I have no idea where they’re going until I start creating.

Grace & Waffles is one of those worlds. What began with a story grew into books, characters, products, a mail club, events, and experiences, and it helped me recognize something I’ve actually been doing my entire life: seeing an idea and wondering how far it could go.

When I’m not creating, I’m usually noticing, traveling with Nyx, spending time with my family, wandering somewhere new, finding beauty in small things, or following whatever has made me curious that day.

Welcome to my world. I’m so glad you’re here.
