Knit Temperature Blanket, Row a Day
One stockinette row per day for a year, coloured by that day’s temperature. 365 rows at worsted gauge lands right at throw length.

- Yarn
- Worsted (4) in 8–12 colours, one per temperature band.
- Needles
- US 8 (5 mm) 40 in (100 cm) circular
- Sizes
- Throw 50 × about 61 in (127 × 155 cm)
- Example gauge
- 18 sts and 24 rows = 4 in (10 cm) in stockinette
- Yarn needed
- About 2,700 yd (2,450 m) in total. The planner splits it by colour using your town’s real temperatures.
Do the math
The examples use the gauge above. Put your own swatch into the gauge calculator first, then use your numbers in each formula.
| Step | Formula | Example | Tool |
|---|---|---|---|
| Cast on | width × sts per in | 50 × 4.5 = 225 sts | Cast-On Calculator |
| Finished length | 365 rows ÷ rows per in | 365 ÷ 6 = 60.8 in | By hand |
| Yarn per colour | total yarn × (days in band ÷ 365) | 2,700 × 60 ÷ 365 ≈ 445 yd | Temperature Blanket Planner |
Materials
- Worsted (4) yarn (see yarn needed)
- US 8 (5 mm) 40 in (100 cm) circular
- Tapestry needle
- Printed colour key from the planner
Gauge swatch
Swatch in stockinette. The row gauge matters here: it sets how long the blanket ends up.
Instructions
Plan
Open the Temperature Blanket Planner. Choose your town, the year, Daily high (or average), Knitting, Worsted and Throw.
Pick 8–12 bands of about 5 °C / 10 °F each. Print the colour key and buy yarn from its per-colour amounts.
Border and set up
In a neutral border colour, cast on (example: 225 sts). Knit 8 rows.
Daily row
RS days: K3 in border colour, knit to last 3 sts in the day’s colour, k3 in border colour.
WS days: K3, purl to last 3 sts, k3 (same colours).
Border edges: use a separate small ball of border colour at each side (intarsia-style), twisting yarns at the colour change. Or work the whole row in the day’s colour and add an edging at the end.
Tick the day off in the planner’s tracker.
Finish
After day 365, knit 8 rows in the border colour and bind off.
Finishing
- Weave in ends every week so they don’t pile up.
- Block to even out colour changes.
Designer’s notes
- Behind on days? Knit them in batches from the tracker; the colours are already worked out.
- Leap year: 366 rows. The top border then starts on a RS row; keep it at 8 rows.
Counter set-up
Counter 1: day of the year (1–365). The planner tracker shows the next colour.
