Dark Academia Mug Cozy Free Crochet Pattern
Introduction
This Dark Academia Mug Cozy is the perfect little project for anyone who loves the look of a well-worn library: sage green and cream stripes, a tidy button tab, and a soft cotton texture that feels warm in your hands. It's a beginner-friendly pattern that uses only single crochet, so you can practice working in the round and changing colors without any complicated stitches. The cozy slips around a standard mug and fastens with a small button, giving it that scholarly, vintage charm. Make one for yourself or gift it to a friend who appreciates quiet, cozy mornings with a good book.
Materials Needed
- Yarn: Worsted weight (category 4) cotton yarn — approximately 50 yards sage green (Color A) and 30 yards cream (Color B). Sample uses Lion Brand 24/7 Cotton in Sage and Ecru.

- Notions: Tapestry needle, scissors, stitch marker (optional), one 1-inch (2.5 cm) button

Abbreviations
- ch — chain: yarn over and pull through the loop on your hook

Gauge
16 stitches and 16 rounds = 4 inches (10 cm) in single crochet. To check your gauge, crochet a small swatch in the round and measure a 4-inch section; adjust your hook size if needed to match.
Tips Before You Start
- When joining the starting chain into a ring, double-check that it isn't twisted — a twisted ring is hard to fix later.
- Change colors on the last stitch of the round (pull the new color through the final loop) for a cleaner transition between bands.
- Keep your tension even so the cozy fits snugly but still slides over the mug.
- Try the cozy on your mug before sewing the button tab so you can position the button perfectly.

Block lightly by misting with water and shaping flat; let dry completely before use.
Pro Tips and Variations
- Swap the sage and cream for deep burgundy and mustard for a richer autumn palette.
- Add a row of slip stitch in a contrasting color along the top edge for a neat, finished look.
- Make a matching set by crocheting a small coaster in the same striped pattern.
