A complete guide to Crochet Temperature Blankets. Patterns, Ideas and Color Charts.

The classic crochet temperature blanket is a fun way of creating a colorful afghan, selecting your yarn based purely on what the weather is like today. Working out how to crochet a temperature blanket is easier than you might think. You just need a thermometer, color chart, matching yarns and a hook. You’ll only use one stitch style for most of them, so it’s quick to make your daily rows and very rewarding when it all comes together. Today I’ll share how to plan out and make your very own unique temperature afghan.

What Is A Crochet Temperature Blanket?

You could be entirely forgiven for assuming that a temperature blanket is in some way heated. Like an electric blanket you can crochet. But it is simply a way of randomly selecting color variations, whilst working on a continuous annual project.

How To Make A Crochet Temperature Afghan

A Temperature Blanket is a crochet or knitted blanket that is made a row at a time. You make one row every day, for a year. The temperature part is what makes it truly unique. Each day have a look at the temperature where you are, and using a chart this will help you to decide which color to crochet with that day.

To keep things consistent, choose how or when you will find the temperature. Your main choices are to pick the highest temperature that day, lowest that day, or the temperature at a particular time of day.

Crochet Temperature Blanket Color Chart

You can choose which colors indicate certain temperatures yourself, but you might also like to work from a temperature blanket color chart. I have put a couple together here. One simple temperature blanket chart with eight different colors, and another more complex choice.

Although you will need more yarn stocked and ready, I think a more detailed and complex color chart will give you the most stunning finish to your crochet temperature afghan. I have created this chart based on the beautiful spectrum of colors that steel passes through as it is heated.

Before you begin, lay out the yarns you have chosen and make sure that you are happy that you will remember the colors each represent. Cutting off a swatch and taping it to the relevant line of color on a printout can be a helpful way of staying on track.

Choosing Your Own Temperature Blanket Crochet Colors

Whilst it is nice and easy to use a temperature afghan color chart, you might like to make use of yarns you already own. You can try and find color combinations that work for you by cutting some short scraps from each color, and arranging them on a piece of paper.

When you have shuffled them around into an order you are happy with, sellotape them down. You can then write your temperatures down the side, and keep this as a handy key.

Another fun way to choose your colors is to pick up a color chart at your local DIY store, and write the temperatures on yourself. This can allow you to make a temperature afghan that varies within a range that is desirable to you.

I love this Diamond Stitch Blanket Pattern. It’s nice and simple, but produces a very high quality, great looking blanket. When using it as a temperature blanket, I recommend that you do two rows per day. Keeping the alternate white rows and reflecting the temperature with the other colored rows.

As it’s an annual project, I recommend extending the row width and working towards a lovely giant double bed sized crochet temperature afghan. You can find the full pattern for this gorgeous blanket at the Happy In Red blog here.

  4. I am starting one using a template of squares. The squares are going to be solid grannies with the innermost rows being the high temp of the day, then the next rows the low temp, and then the outermost row being the birth stone month’s color. I am using a small hook and finer yarn for the squares themselves since there are so many of them. I will border them with plain white or black and join as I go.
