Crochet Temperature Blankets: Picking Colors & Yarn

Temperature blankets are a snapshot of the weather over a given time period in a given area through your crochet. The great thing about temperature blankets is that you can pick any colors, yarn, stitch pattern and time span that you want.

Once you decide that you want to make a temperature blanket to record a year or time period you will need to choose what yarn you will use. Picking colors and yarn for your temperature blanket is important because you need to know how many colors you will use, what range of colors you will need, and how many balls of yarn you might need.

Picking Yarn Colors and Deciding How Many

Picking your colors and how many is determined by range between your high and low temperature. Take a look at the highs and lows that you are seeing for the year, or the year before, to get an idea of where to start.

Most often people pick between 8-10 colors to represent their temperatures. Each of these colors will represent between 5-12 degree changes. This all depends on how much of a difference you have between your high and low for the year, so yes that means that there is some math before you get started on your project.

Although you will see that many temperature blankets are done with rainbow colors, having reds be the warmer temperature and blues being the colder temperature, you can pick any colors you enjoy. Be sure to think about the value difference in the colors so that you can always be sure to see the difference. A really great way to do this is to take a black and white photo of your color selections. This will show you if there is any value difference between your colors.

Picking the Right Yarn for a Temperature Blanket

Because you will need multiple colors of yarn it is important to pick a yarn that is affordable for your budget and also that has a wide range of colors to choose from. You might also consider if the yarn is machine washable for ease of care, and remember that the weight of the yarn will affect your chosen stitch pattern and the size of the final finished blanket.

It is hard to tell exactly how much yarn you will need for this project. Just like meteorologists, we can’t predict what the weather will be for the entire year, so we need to make a guess. If you aren’t sure what your average high or low is for your area try out a weather tracker to get those answers. A lot of your yarn requirements will also depend on where the temperature falls in your scale. If it is an uncommonly cold or super warm temperature you might only use it once or twice so you might only need one or two balls of that color.

You can look at last year’s temperatures, or examine several recent years’ temperature history to get a feel for how often certain temperatures might occur. Then make an educated guess.
