Tempestry helps knitters and crocheters create weather blankets with less hassle and more consistency.

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. You assign yarn colors to temperature ranges and craft one row per day, creating a colorful record of an entire year's weather.

Tempestry automates the tedious parts so you can focus on the craft.
