These adorable cozy drink sleeves are absolutely perfect for fall and winter, and can be made with just a few materials. Take an old flannel shirt (men's sizes work best), cut off the cuff, and glue any frayed edges. The finished product will fit over a standard size paper coffee cup. There's no sewing or guesswork involved. Best of all, the craft is relatively inexpensive when shirts are sourced from your local thrift or discount store!
