My mom loves her Manhattans every night before dinner. She likes them with a lot of ice, and thus the glass sweats. She asked me to make some tumbler cozies for her. They must have a bottom, so as not to leave rings of condensation on the table. This project is great for using scraps of yarn left over from knitting dishcloths! It is worked from the bottom up, starting with a few rows flat before joined in the round. It finishes off with a stretchy bind-off (video).
