Temperature Pi Blanket – March Update

There is a saying that “If March comes in like a lion it goes out like a lamb”, and vice versa. March certainly arrived tamely with three days of dense fog, not unusual where I live on the side of a hill; we often find ourselves up in the clouds, and the accompanying lack of wind means it can last quite a while.

The blanket is getting big! I am already using two 150cm circular needles to comfortably accommodate the 576 stitches. The first half of the month was cold, but by the 16th temperatures were beginning to rise, and the month ended in the low 20s and very sunny. In fact the temperatures on the last two days of March were a UK 50-year record for the month.

The warmth at the end of the month – reaching just over 23 C on one day – is certainly helping to dry out the soil and open the buds on the trees and bushes. The daffodils are colouring the border of our driveway and the leaves are unfurling on the apple trees. Suddenly, it is all looking very green and yellow!

The colours of the blanket have changed from shades of blue to shades of green, too, even veering to yellow on the last two days of the month, and there have been a lot of sunny days, even if they have not been particularly warm. I have used nearly an entire ball of Rowan Kidsilk Haze Eve Green (denoting sun) just for the first three months of the year! In fact, there have been 30 days in the first 90 days of the year when the weather was predominantly sunny. That seems like a lot, given our latitude, and my experience of more than 20 years living in the same place!

I am now up to day 90, and have 576 stitches on the needle; the blanket is approximately 72 cm in diameter (unstretched), and I am very happy with my progress.

Temperature Pi Blanket – February Update

Good progress has been made this month, and it has been interesting to see the temperature variability. We had a week of really cold days, when the temperature rarely rose above zero, followed by almost balmy days of 10 – 13 degrees Celsius to close out the month.

The old name for February, in some parts of England, was Filldyke, and we can certainly get a lot of rain. This year, we had snow and ice instead, which of course fills dykes and ditches when it thaws! The soil is waterlogged, although a good few days of wind and sun have dried out the surface.

The left photo above shows the blanket so far, both January and February. The right photo shows an interesting section of February, 15th to 19th; the temperature stayed within the same band, dark blue 6 – 10 degrees, but the Kidsilk Haze modulates each day – overcast, overcast, sun, rain, wind – in a pleasing way so that no two days look alike.

I am now up to day 59, and have 288 stitches on the needle, and the blanket is approximately 48 cm in diameter. I really like how the colours move and fluctuate, and the Kidsilk Haze gives a lovely halo of warmth and comfort.

Temperature Pi Blanket – January Update

I started my 2021 Temperature Pi Blanket project a little late, because I was waiting on delivery of several of the yarns, but I made sure I had recorded temperature and weather each day on my spreadsheet so that, once I had them, I could steam ahead. January represents relatively short rounds and several rounds could be knit in a day, so there was no problem in keeping up with events.

The weather here in January can be very variable; we can be buried in snow or deluged with rain. 2021 started quite mild, and although the overnight temperature dipped below zero Celsius once or twice, the maximum temperature hovered mostly around 4 or 5 degrees Celsius. We had some snow, and the first storm of the year, Storm Christoph, but also several days when it was sunny but cold. As the month drew to its close, it became milder but also wetter with odd flurries of snow, and then the last two days were very frosty and cold.

January

I have completed 31 rounds, beginning with 9 stitches per round, and have now reached 144 stitches per round. It will be interesting to see what February will throw at us!

Temperature Blanket for 2021

I’m always looking for a new project for the New Year, and this year’s project will truly span the whole 365 days. I am going to knit a temperature blanket to reflect the weather where I live. But this won’t be the usual square or rectangle; it is a Temperature Pi circular blanket, based upon the principles laid down by Elizabeth Zimmerman, and I should be delighted if you would like to join me in this enterprise.

To begin at the beginning, you need good data for your locality. I am enormously lucky in that I have an electronics geek for a husband; he created a garden weather station for me some years ago, and since the station outputs its data to a website, I have everything I need to begin. Alternatively, you could use the BBC Weather website or other weather app to gather data. I have prepared an Excel spreadsheet for you to use in gathering data. It is certainly not too late to start.

As well as temperature, I have been recording the predominate weather condition each day. The blanket I have designed can be knit in two ways; you can use just the temperature for each day’s round, or you can add in an indicator of the weather condition to the temperature. I have done this by holding both the temperature yarn together with a strand of fine yarn such as Rowan Kidsilk Haze, to knit each round. This gives a lovely haloed warm texture, as well as a subtle colour modulation.

The second requirement is a good selection of colours for your temperature range and your weather indicator. I selected a palette of 9 temperature colours to range from -5°C to 40°C, in 5 degree increments; you may need to adjust your range based upon where you live; if you generally have temperatures lower than -5°C but never get above 30°C, then alter your range accordingly. I selected seven weather indicators – sun, overcast, rain, wind, fog, snow, and storm (which could be a combination of wind and rain, or wind and sun where I live) – and chose colours to reflect these from the Kidsilk Haze range.

Lastly, you need a pattern to help keep you on track. The Excel spreadsheet helps in keeping track of the day numbers and dates, the pattern gives colour and yarn suggestions, as well as details of increase rounds. There is a pretty lacy edge, charted and written, for the month of December to look forward to. The free pattern has been tech edited, and is available together with the spreadsheet by clicking here.

My progress so far on the blanket looks like this; you can see the marled effect of using the weather indicator thread together with the temperature: Small beginnings, but it will grow!
