Here are a few Mug Hugs that are available. All are my own design. If you are interested in purchasing one, please visit my Etsy shop. The link is below the photos.

I learned not to use shank style buttons because they are too hard to sew in place.
This button has been most people's favorite, especially with this yarn.

See how Mug Hugs have a coaster bottom, something you don't find in other cozies.

This yarn colorway is "Bistro". It really sets off the wood button.

More styles can be seen at CozyCornerCrochets shop.
