Why Get a Mystery Box?
There’s something magical about opening a surprise box. Unlike shopping for individual supplies, a mystery box encourages you to think outside the box (literally!) and experiment with products, colors, and techniques you may not have chosen for yourself. It’s a chance to discover new favorites, explore fresh ideas and spark creativity in unexpected ways.
Many makers tell us that mystery boxes inspire projects they never would have attempted otherwise—and often lead to some of their most-loved creations (see below for some testimonials we received from a past box!). Think of this Under the Sea box as a summer vacation for your imagination. Still on the fence? Check out some of our past boxes and see what was inside – you won’t believe all the items and the incredible value! TAKE ME THERE>

Exclusive Mystery Projects Included
Every Under the Sea Mystery Box comes with two digital project PDFs designed exclusively for the items in the box.

Whether you’re creating for yourself, decorating your home, or stitching handmade gifts, these projects are designed to inspire and delight.
The Inspiration Doesn’t Stop There
One of the best features of this year’s Mystery Box is the specially curated online inspiration hub.
