On January 2013, Kristen Cooper Nutbrown from British Columbia had the idea of creating a temperature scarf by knitting one row every day using a color that encodes the temperature of the day. At the end of the year, the scarf visualized local temperature readings for the whole year. Soon after Kristen pitched her idea, Arlene Cline, also from British Columbia, started to create a temperature afghan (a blanket of knitted or crocheted wool).
Temperature scarves and afghans became quite popular in the knitting community, and several tutorials exist on how to make them. The temperature scarf on the left photo above is from ravelry.com user SleepyEyes (completed 31 Dec 2014). The afghan on the right is from Sharon MacDermaid (completed 31 Dec 2016).
