Pattern Basic Points

Construction Overview

  • The cozy is built from traditional granny squares worked in joined rounds.
  • After three rounds of classic granny square method, the squares are sewn together for a wrap-around shape.
  • A sturdy border is crocheted all around for durability and neat appearance.
  • The border includes half double crochet (hdc) and slip stitch (sl st) rounds.
  • A chain button loop is crocheted at the end for functional closure.

Special Notes

  • Use thick cotton yarn to ensure the cozy is absorbent, insulating, and easy to wash.
  • Check fit against your mug after assembly and before finishing the border and loop, especially the length of the button loop.
  • All yarn ends should be securely woven in.
  • The numbers of squares and sizing can be adjusted for different mug sizes.

Skill Level

Beginner to Intermediate
This project is perfect for adventurous beginners who want to learn classic granny square construction, joining techniques, and tidy borders.

Materials

  • Measuring tape: To check size against your mug

Measurements / Sizing

  • The completed cozy fits a standard mug (adjust squares or add extra rounds for large mugs).
  • Each granny square will measure about 5–6 cm after blocking (depending on your yarn and tension).
  • Final length should wrap fully around the mug, with overlap to attach button/loop.

Gauge

  • hdc: half double crochet

Special Stitches

  • Granny Cluster: 3 double crochet stitches worked into the same space.

Pattern Instructions

Granny Square

Round 1

  • Chain 4.
  • Join with a slip stitch to form a ring.
  • Into the ring:
    • Chain 3 (counts as first dc), work 2 more dc into the ring (first granny cluster). (Total 3 dc)
    • Chain 2 (forms corner).
    • 3 dc into ring, chain 2 — repeat this sequence twice more (so you have four 3-dc clusters, each separated by ch-2 corners).
    • Slip stitch to join to the top of the first dc (or ch-3). Fasten off.Granny Square Crochet MUG COZY (7)

Round 2

  • In each of the next three corners:
    • Work 3 dc, chain 2, 3 dc into the corner.

(Repeat above steps to create as many squares as needed for your mug’s circumference—usually 2 squares for a standard mug, but measure to be sure.)

Assembly

  • Place the squares edge to edge (wrong sides together).
  • Use a tapestry needle and yarn to sew your completed granny squares together (edge to edge, matching stitch for stitch).
  • Weave in all ends on the wrong side.Granny Square Crochet MUG COZY (3)

  • In each corner:
    • Work 2 hdc, chain 2, 2 hdc.
  • Continue hdc in every stitch/space to make a smooth edge.
  • Slip stitch to starting stitch to join.

Round 5 (Border Round 2 and Button Loop)

  • Slip stitch (sl st) into every stitch all the way around the border.
  • When you reach the end, create the button loop:
    • Chain 18 (or whatever length fits your mug handle as a loop).
    • Test the loop size by placing the cozy on your mug; adjust chain length if needed.
    • Attach the end of the chain with a slip stitch to the border so the loop is secure.
