What Is a Weather Blanket?

A weather blanket (also called a temperature blanket or tempestry) is a year-long knitting or crochet project where each row represents one day's temperature. Crafters assign yarn colors to temperature ranges and knit one row per day, creating a colorful record of an entire year's weather. The finished blanket becomes a unique, personal textile that tells the story of a specific place and time.
