This is a pattern for a blanket that records in color the daily high temperatures in my hometown (Decorah, Iowa, USA) and the city I now call home (Sydney, Australia). The blanket is made up of mitered squares that are knit-together-as-you-go. I have a few blog post about how this blanket came to be: here, here and here.

I have not “invented” the mitered square pattern or the idea to use a bunch of mitered squares together to make a blanket. But - as far as I know - the idea to use the squares to represent daily high temperatures is a new idea.

You can come up with your own color scheme or use the one that I developed (included in the pattern). I have used 15 different colors of DK (8-ply) acrylic yarn on US size 6 needles.

There are so many variations you could do for a blanket like this. The stripes in each square could represent:

• The high and low temp for each day for a single location for a year.
• The daily high temp for the year a couple was married (you can find archived temperature data online) and the year they celebrate a milestone anniversary.
• The daily high temp for a child’s first year and the year they celebrate a milestone birthday.

I look forward to seeing what you come up with.

Please note, this pattern has not been tested - please let me know if you find any errors.
