Frankenstein Coffee Cozy - Free Crochet Pattern

Updated: Mar 24

Hello, hi & welcome back! I'm so excited to share my Frankenstein Coffee Cozy Free Crochet Pattern with you! This pattern works up quickly and is the perfect creepy-cute Halloween gift idea!

This Frankenstein Coffee Cozy is comprised of the coffee sleeve base which is crocheted in rows to create a flat rectangle. The coffee sleeve base is seamed together at the end using a tapestry needle. The finished coffee cozy measures approximately 4" tall by 4" wide when lying flat. This pattern can be adjusted to fit the width of your mug of choice (see the coffee sleeve base pattern detail below for adjustment instructions).

Yarn Colors:

I receive many questions regarding the specific yarn colors I use for my projects! Oftentimes, I use leftover colors in my yarn stash that I have lost the labels for or have acquired secondhand without labels, so I apologize if I cannot list them all each time! Below are the specific brands/colors I do know for this particular pattern!

  • Red Heart Super Saver in the color 'Frosty Green'

  • Purple (Sorry, I'm not sure!)

  • Red Heart Super Saver in the color 'Black'


This pattern is written in US crochet terminology.

  • Chain

  • SC - Single Crochet

  • Drop Stitch (we will just be dropping to the row directly beneath the working row)

  • * - Repeat sequence until the end of the row.

Mug Size Adjustment

This pattern is designed to fit a standard Starbucks reusable mug. However, you can easily adjust your chain stitch amount on the base of the coffee cozy pattern to fit the mug of your choice! You'll chain the amount that fits perfectly around your mug + 1 chain stitch. For instance, if 28 stitches fit perfectly around your mug you will chain 29 and each row will be 28 stitches.

Coffee Sleeve Base:

With purple, chain 35

Rows 1-4: SC in each stitch, chain 1 (34 stitches)

Row 14: SC in the first 3 stitches, drop stitch in the next*, chain 1 (34 stitches)

Row 15: SC in each stitch, chain 1 (34 stitches)

Tie off with a long black tail.

Assembly / Invisible Seam:

  • Fold the coffee cozy with the wrong side out (side you like best on the inside) and line up the rough edges.

  • Using a tapestry needle and the long tails, stitch the rough ends together. Pay close attention to the top and bottom of the join to ensure it won't pull apart when stretched over the mug.

  • I like to tie off by double/triple knotting the tails together on the inside and trimming any excess yarn.

  • Turn right side out.


Secure the safety eyes in place; I use a wire cutter to snip the excess post from the back of the eyes. This helps the eyes to lie as flat as possible against the mug.
