Here's how it works
Knitting
Cast on 16 stitches with the Knitting needle . Smooth right (back row right stitches, back row left stitches) knit up to a height of approx. 20 cm.
Extra tip: Single left back rows make pretty cross ribs. To achieve this, knit the stitches in the back row and the back row on the left so that they stand out on the front side knitted on the right.
As soon as the knitted piece reaches almost around the cup, cast off the stitches loosely
Crochet
Pick up the last stitch with the crochet hook and crochet with firm stitches around the knitted piece. In the corners crochet 3 stitches.
On the last short side crochet three air sts chains with approx. 15 air sts and form a loop with a chain stitch. Crochet between the loops with warp stitches along the edge. After the last loop, cut the thread and stitch it.
Sew three wooden buttons on the other short side, put the cup warmer around the cup and button it up.
Wrap a colorful pompom with the larger of the two Pompon Maker and knot it tightly.
Cut the pompon into shape and fix it on the lid of the cup with hot glue.
