Basic instructions for a temperature blanket

I have used three colour pallets for this blanket.
High–Low
14 colours ranging from -1 to 40+ deg C (3deg increments)

Rainfall
White = no rain, Light grey = up to 14.9mm, Dark grey = over 15mm

Month
12 colours – Or you could do 4 seasons.

Each motif measures approximately 3. inch (7.5cm).
Amount of yarn required will vary for different regions. You will need more for middle of the range temperatures and less for extreme temperatures.
I have worked my motifs on the diagonal.
Instructions for borders are not included.
