The PlanetJune Temperature Snake CAL (crochet-along) ran from January 1 - December 31 2023, with over 800 participants from over 26 countries. The Temperature Snake is an amigurumi-style riff on the temperature blanket/scarf, where you crochet one row per day to represent the maximum temperature that day.
Some participants chose to make twin high/low temperature twin snakes, birth year snakes (representing the temperatures over the first year of a child's life), or even book snakes (representing the quantity and genres of books read over the year) - anything that can be represented with a colour code and logged over the course of a year can be crocheted into a Temperature Snake!
