Here is a simple yet interesting-looking reusable sleeve for hot take-out drinks that you can make for yourself or someone you like. The wool insulates your drink and keeps your had from burning while the bobbles make it easy to hold on to. Knit in the round, this project takes a little bit of yarn and a few hours. You can make a bunch of sleeves from one ball of yarn, which makes it both ecologically and economically friendly.
All proceeds from the sale of this pattern will be donated to the World Wildlife Fund.
