Exploring Temperature Blankets

Temperature blankets are a simple concept that require a bit of planning and a lot of patience. The idea is to make a year-long blanket using colours that represent each days’ temperature. Typically, the maker will research the previous last year’s temperature ranges and select a colour palette for their yarn, and start making their blanket at the beginning of the new year, one day at a time. Most makers will gather the data for the week and make a week’s worth at a time. Generally, using a weather app to obtain the average, coolest or hottest temperature of each day, which determines the colour they will use. I’m puffed out just typing that, it’s sounds more complicated than it is.

If only I could live on the edge like that. Not knowing what the week will bring. But, if you’re like me, and don’t feel comfortable making a temperature blanket using last year’s numbers as a guide and prefer to plan your blanket with the exact amount of yarn needed, this is for you! 

So, what do I do?

First, select a year and location that is close to your heart. For me, I chose the year when I met my husband, 2011, and the location we had our first date, Mornington, VIC. That was very easy.

This next step is easy too, visit, an amazing website that has been created by Joseph. Joseph has done all the hard work for you, to create the perfect temperature blanket. And he is constantly updating his site to include more useful features, functions, yarns and patterns to help you make the right decision. There’s options of how many colours you can use, how many rows and stitches to make your blanket, colour palette samples and even assigning popular yarns to the palettes so you don’t need to stand aimlessly in the aisles of your LYS wondering if that yarn colour matches what’s on your digital screen.

To go into more detail, let’s go through the process together and I’ll show you how to get the data needed to make your own blanket.

Step 1

When you first visit the website, you will be greeted with a short form. On the top right, make sure you select Celsius/Millimeters or Fahrenheit/Inches. Enter in your location, year and start date you wish to make and select search. The smart program will download the weather history data and show you a graph.

Step 2

Now is the fun part, selecting yarn colours and assigning each colour to a range. Select the amount of colours you want, the more you choose the more colour changes will happen throughout your design. You can select Random Colours or Browse Pre-made Schemes or choose your own. If you know the brand of yarn you wish to use, select the dropdown box and find the one or closest one you want.

Once you’ve selected the yarn, scroll down a bit and view the assigning table. In the table next to the Colour # number, the up and down arrows will change the order in which your colours are assigned. Click on Range Options to adjust your range. You can change the direction from high to low or low to high, start from a certain degree and lower or increase the increments for each colour. Once you can see a number of days next to each colour to the right in your table, you are ready to scroll down and select your pattern design!

Step 3

If you think this is all brilliant so far, you can support Joseph on Ko-Fi at This allows him to develop more amazing tools for you to use in your crafting journey. It even says it here under Step 3! I highly recommend supporting Joseph as I know I will be coming back to use his site every year.

Time to design. Select the pattern type you would like to try, tick the maximum, average or minimum temperature, stitch count and row length. I had so much fun finding a design and seeing what it would look like. I’m still undecided as of this blog post.

Once you selected what you want, click Download Image (PNG) at the bottom. You can also share to the gallery so others can see what you chose!

But… How do you know how to make it? The most important part here is to download the data. Scroll back up to the bottom of the Step 1 section, and you will see you have the choice to download the weather data on Excel CSV or PDF. The data is so easy to follow as it gives you all the temperatures for each day. In the PDF, it highlights the degrees with the colour assigned to it. It’s best to download the data after assigning your colours so they match up with what you plan on making.

EDIT: Beth Hale Farnum from NutNut Narratives saw my post on Instagram about this topic and reached out to let me know about her new journal that was published on 5th of December, 2022!

A Year in Yarn: The Temperature Blanket Journal is a 200 page paperback journal with loads of information to help you make choices for your blanket project AND includes pages for you to journal each day. If you are a hands-on, need to write down person, this is for you. Reflect on your journey and record the daily high, low or average temperatures with room to write out special moments. What a wonderful companion to accompany your journey throughout the year.

Now, the colours and style above are not quite what I will be going with and I still have time to work it out, but I hope this guide will point you in the right direction and spark some enthusiasm into starting a year-long project!

Happy Crafting xoxo
