Create a magical Plus-Plus Rainbow Unicorn with these free 2D instructions and downloadable PDF pattern.

This 168-piece animal mosaic blends a classic unicorn silhouette with a vivid rainbow mane and tail. The design is one of the most searched Plus-Plus unicorn patterns, combining fantasy appeal with a structured color grid that makes the build approachable despite its detailed appearance.

Rated as hard difficulty with an estimated build time of around 14 minutes, this unicorn build guides you through the body first, then the horn, mane, and tail sections where the rainbow colors really shine. Working through the mane one color at a time keeps the pattern clear and the result vibrant.

Follow the instructions on screen or print the PDF for a hands-on building session. Sorting all 168 pieces by color before you begin is essential for keeping the rainbow sections organized and accurate.

The completed Plus-Plus Rainbow Unicorn makes a wonderful gift, bedroom decoration, or centerpiece for a fantasy-themed collection. Press each piece firmly and enjoy watching the colorful mane come together row by row.
