This coffee cozy is made of nearly 100% cotton yarn, in stripes of red, yellow, khaki green, blue-gray (75% cotton, 25% acrylic), purple, beige, and cream. The exact stripe pattern of your coffee cozy may vary slightly from the one depicted--I make these by grabbing one color to start, and then working through all of the colors in a random sequence and stripe pattern. It can stretch to fit onto any size of paper coffee cup. Unstretched, the cozy is 2 1/2 inches tall (6.4 cm), 9 inches around at the top (23 cm), and 8 inches around at the bottom (20 cm).
I would recommend washing this specific cozy by hand, because the red is likely to bleed. The red yarn has been pre-washed to minimize bleeding, but it may still give off some dye. It is probably safe to put into the dryer, but you can air dry it if you want to be extra careful.
