The Knot Workshop has created a cute and boastful coffee mug accessory. The piece is a knitted warmer that packs a cup full of humor. If you like this mug accessory, you can purchase it from the Knot Workshop Etsy page for the small amount of $14 (but you should probably act pretty quickly as there's only one currently left).
The humorous warmer by the Knot Workshop is particularly interesting because it seems like something a child would make as an arts and crafts project, but the little message on it proves otherwise.
The Knot Workshop has definitely nailed it with this mug cover and will hopefully produce many more of these fantastic covers for us all to purchase.
