    Finish your cozy with a bit of embellishment. Thread a darning needle with scrap yarn and use duplicate stitch to make a heart, flower, initials — anything you want!

    How to Customize Your Mug Cozy’s Size

    1. Determine how wide you will make your cozy by subtracting 1¼” from the height of the mug.

    2. After checking your gauge, cast on enough stitches for a circumference that is about ½” to 1″ less than your mug circumference.

    3. Work in the round with your preferred edging for about ½”. Then begin working in rows, decreasing two stitches on the first row, to make room for your mug handle.

    4. Work even until the flat portion measures the height of your handle. Increase two stitches and then begin working in the round again.

    Pro Tip: If your mug has a very tall handle, work the entire cozy flat and add a button or other closure to keep it snug.

    5. Continue with this until your cozy measures the width you determined earlier. Bind off, weave in the ends and you’re done!
