In this instructable you will design a pattern and sew one cozy. The pattern can be reused because pints of ice cream are pretty much standardized.
These instructions would also work for making a cozy for to-go coffee cups. Just use a cardboard coffee cup instead of a pint of ice cream to make the pattern. You can use your own fabric cozy and skip the cardboard sleeves at the coffee shop - save the trees!
