Welcome to Whimsy

What is Decoden?

At Whimsy DIY Studio, everything we do centers around decoden—but if you’ve never heard of it, let me tell you the story. Decoden started in Japan as a way to decorate phone cases and accessories with whipped cream-like clay and sparkly charms. The word comes from “decoration” + “denwa” (Japanese for phone). Over time, it grew into a playful art form that’s all about layering swirls, sprinkles, and charms to make everyday items magical.

Why We Love It

For kids, decoden feels like dessert for your imagination, you get to pipe colorful “whipped cream,” sprinkle on gems, and press in adorable charms until your masterpiece shines. For parents, it’s a low-mess, high-fun way to keep a group of kids engaged, creative, and proud of what they’ve made. (Bonus: the finished pieces double as keepsakes—way more meaningful than a goodie bag toy that gets lost the next day!)

What We Do at Whimsy DIY Studio

We took the magic of decoden and bundled it into party-ready kits. Each Whimsy DIY kit comes with everything you need—creamy swirls, charms, sprinkles, tools, and even the item to decorate, like picture frames, brushes or phone cases. No frantic shopping, no mystery supplies, no “oops, I forgot the scissors.” Just open the box, gather the kids, and let the fun begin!

Why It Works for Parties

Forget the stress of bounce houses or messy slime parties—Whimsy kits make parties stress-free for parents and exciting for kids. The best part? Everyone leaves with their own decorated treasure, a magical keepsake to remember the day by.
