Cobalt Coast Mahjong Mat

Bring crisp coastal style to the table with Cobalt Coast, created as part of the Mahjong by SI™ x JJ Designs collaboration with Atlanta-based artist Jessica Henderson.

This polished design features a painterly scallop shell set against a bold cobalt blue background, framed with classic gingham and scattered shell motifs in shades of blue and sandy tan. The layered pattern gives the mat a fresh, preppy feel while keeping the overall look clean and easy to style.

The combination of rich cobalt, soft neutrals, and coastal artwork makes Cobalt Coast feel perfect for beach houses, summer gatherings, porch games, and anyone who loves blue-and-white design with a seaside twist.

Jessica Henderson of JJ Designs began with a love of painting from a young age and has grown a collection of original artwork inspired by florals, mahjong, and traditional design. With a love for blue and white, grandmillennial style, and preppy interiors, Jessica creates fresh takes on timeless pieces for the home.

Based locally in Atlanta, JJ Designs has partnered with leading mahjong dealers and boutiques to bring artwork to clients nationally. Jessica is excited to bring all of her favorite things together in this collection.
