Here are cozies I have made. The crocheted granny-square cozy is a pattern adapted from Alexandra Mackenzie's "Granny Square Tea Cosy" (purchased through Etsy), meaning that I had to downsize the squares for a more custom fit. The gray cozy is also crocheted, one that is quick and easy to make. The teapot pictured holds 3 cups of liquid when filled to the top. Cozies keep the teapot warm, that's for sure.
