For one that fits on the teapot, you'd have to know what shape teapot they have. You wouldn't want to make a cozy for a short fat pot only to find out they have a tall slender pot. Plus where the spout is - I've seen round ball shaped teapots with the spuout starting low near the base and others where it's up high.
