Crocodile Stitch Mug Cozy Free Crochet Pattern

Introduction

The Crocodile Stitch Mug Cozy is the perfect little project for anyone who has mastered single and double crochet and is ready to try something with a bit more texture. Those raised, bumpy scales look impressive, but they are built from simple 5-double-crochet groups, so you can absolutely make this as an advanced beginner. Worked as a flat rectangle and folded into a tube, it wraps a standard mug snugly and keeps your tea or coffee warm while looking charming on the shelf. The sage green scales against cream borders give it a cozy, cottagecore feel that makes a lovely gift or a treat for your own kitchen.

Materials Needed

• Yarn: Worsted weight (category 4) cotton yarn, approximately 50 yards total — 40 yards color A (sage green), 10 yards color B (cream)
• Hook: 6 mm (J/10) crochet hook
• Notions: Tapestry needle, one button (about 1/2 inch), scissors
• Finished size: Approximately 3.5 inches wide x 3.5 inches tall (flat), fitting a standard 3.5-inch diameter mug

Abbreviations

• ch — chain: make a loop of yarn and pull it through the loop on your hook
• sc — single crochet: insert hook, pull up a loop, yarn over, pull through both loops
• dc — double crochet: yarn over, insert hook, pull up a loop, yarn over and pull through two loops twice
• sl st — slip stitch: insert hook, pull up a loop and pull it straight through the loop on your hook
• sp / sps — space / spaces: the gap made by a chain
• st / sts — stitch / stitches
• rep — repeat

Gauge

4 pattern repeats (crocodile stitch) = 4 inches, and 8 rows = 4 inches. To check, crochet a small swatch of the scale rows and measure across the scales and up the rows before starting your cozy.

Tips Before You Start

• Cotton yarn holds the scale texture best and handles the heat of a mug — avoid acrylic if you can.
• The scales are worked into the ch-2 spaces, not into individual stitches, so keep those spaces loose and easy to find.
• Count your 15 stitches after every solid sc row; the pattern depends on that number staying consistent.
• Leave slightly longer tails when changing colors so you can weave them in securely later.

Button Loop

Loop (B): Join B to top right corner, ch 8, sl st to form loop, fasten off.

Button

Sew the button to the opposite side of the cozy so it lines up with the loop.

Assembly and Finishing

Fold the piece in half with right sides facing, then seam the two side edges together using B yarn and a whipstitch. Turn the cozy right side out so the scales sit on the outside. Weave in all ends securely on the wrong side. Block lightly by misting with water and shaping flat, then let it dry fully before using it on a mug.

Pro Tips and Variations

• Swap the sage and cream for any two contrasting colors to match your mug or kitchen.
• Add a third scale row by repeating Rows 6–8 once more for a taller cozy.
• Use a slightly larger button or a two-button closure if you like a snugger fit.
