I thought I would make a cozie in single chain to fit tighter around my mugs. I have some in double chain and they “slacken” after a while and with washing. I used snaps for this one, but you can use buttons or Velcro. I love using variegated yarn but you can use the color of your choice. You can make it with 2 bands or just one.
Let me know if you need help with the pattern. tetley_56@yahoo.com
Top 2 photos are the finished cozie, the next is of it on a different mug for sizing, the next is of the snap placement then the type of snap I used and type of Velcro you can use.
