Thermal travel mugs keep your drink hot for about 3 hours, but you can grab an extra hour of heat if you cuddle your mug in a layer of woolly warmth.
This cosy perfectly fits the standard 0.35l (0.74 pt) thermal travel mug made by Aladdin and Lifeventure, amongst others.

This is a very simple and fast beginners’ level pattern, knitted flat on straight needles.

Perfect for using up odd and ends - either use leftovers of a chunky (bulky) yarn, or run two or more strands of thinner yarns together.
