YEAR-LONG PROJECT

How to plan and track a temperature blanket in 2027

A temperature blanket records a year of weather: each day gets a row (or a stripe, or a square) in a color that stands for that day’s temperature. It’s a lovely, slow project, and the hardest part isn’t the knitting. It’s keeping track of 365 days.

1. Choose your temperature and your ranges

Pick one reading and stick with it all year. Most people use the daily high. Some use the low, or knit both as two rows. Look up your area’s typical highs and lows, then split that span into 7 to 12 ranges. Ranges of about 10°F (5°C) work for most places.

Example temperature ranges and colors
Daily highExample color
Below 20°F (below −7°C)Deep navy
20–34°F (−7 to 1°C)Blue
35–49°F (2–9°C)Light blue
50–64°F (10–17°C)Green
65–79°F (18–26°C)Yellow
80–89°F (27–31°C)Orange
90°F and up (32°C and up)Red

An example only. Adjust the ranges so your most common temperatures are split across several colors, or most of your blanket will be one stripe.

2. Decide how much to knit each day

Knit a swatch, measure one row, and multiply by 365 (or 730) before you commit. That tells you whether your blanket will be a throw or a runway.

3. Work out your yarn

Swatch a few rows, weigh them, and work out the grams per row. Multiply by the days each color is likely to get, using last year’s weather as a guide, and add a skein of the colors for your most common temperatures. Yarn shops and online sellers often sell temperature blanket packs in December.

4. Keep a log, separate from the knitting

This is what makes or breaks a temperature blanket. Keep two numbers:

A row counter set to “days knit” does the second job. If the counter says 41 and it’s February 20th, you know you’re 10 days behind, and your log tells you which colors those 10 rows are.

Example: catching up after a busy week

Your counter says 59, so day 59 (February 28th) was the last row you knit. Your log shows March 1st to 7th as 41, 38, 44, 52, 55, 47 and 43°F. With the example ranges above, that’s light blue, light blue, light blue, green, green, light blue, light blue. Knit those 7 rows in order, then set the counter to 66.
