Hi, I’m Chelsea the heart behind Happy Hands Party Co. 🤍

Happy Hands was created from a simple idea: sensory play should feel beautiful, intentional, and effortless—for both children and their parents.

As a mom, I found myself searching for activities that encouraged creativity and imagination, without the mess or overwhelm that often comes with them. When I couldn’t find it, I created it.

At the heart of Happy Hands is our signature non-stick sensory slime—thoughtfully developed to be soft, moldable, and never sticky. It offers all the joy of sensory play, reimagined in a way that feels clean, elevated, and parent-approved.

Our mobile slime bar is designed as a curated experience, not just an activity. Each child is guided through creating their own custom slime—selecting from a refined palette of scents, textures, colors, and charms—resulting in something uniquely theirs.

Every detail, from the materials we use to the way our bar is presented, is intentionally chosen to create a seamless, memorable experience that feels as special as the occasion itself.

Whether you’re hosting a birthday celebration or a thoughtfully styled event, Happy Hands brings a modern, elevated approach to sensory play.

My goal is simple:

Bringing joyful, creative, sensory play to parties in the Treasure Valley.
