Mosaic Squares Coaster | Mosaic Crochet Pattern

The perfect little project to learn overlay mosaic crochet — and protect your morning coffee too.

The Mosaic Squares Coaster is quick, satisfying, and oh-so-clever. With its graphic geometric design and built-in fringe finish, this little mug rug proves that mosaic crochet is easier than it looks — and a whole lot more fun than it sounds.

What You'll Make

A small flat coaster or mug rug worked in overlay mosaic crochet, featuring a bold repeating squares design in two contrasting colors. The yarn tails are tied off along the sides to create a natural fringe edging, giving this piece a textured, handcrafted finish that's as functional as it is pretty. Make one for your desk, a set for your kitchen, or a stack of them as a quick handmade gift.

Skill Level

• Colors alternate every row; yarn is fastened off at the end of each row (yarn tails become the fringe — no weaving in needed!).
• Every row begins and ends with a border single crochet through both loops.
• The pattern has a 12-stitch repeat — easy to scale up for a larger mug rug or table runner.
