What is a Temperature Blanket?

Have you heard of temperature blankets? They're a super popular project idea, and it's easy to see why -- they're fun to make, a long-term project, and have the potential to be passed down as an heirloom piece. But what are they?

The basic idea is that you knit or crochet one row per day of a blanket in a color that coordinates with the temperature. If you use about eight to ten different colors, you'll get a beautiful variation throughout the year. Depending on the climate where you live, each color will probably correspond to between five and twelve degrees. Below is a sample color chart, made for the climate in New York City and using Vanna's Choice®️ yarn:

To make the colors really stand out, it's best to use a fairly simple blanket pattern. Even a basic garter stitch or single crochet back and forth would work well. If you would prefer to use a written pattern, the ones below are simple enough to show off the change in seasons.

    How would I change it for the Savannah, GA climate?

    I love this idea! How do I know how much yarn to purchase? I'm worried that I might not get enough in one color/dye lot and too much in another color. With return policies being more and more restrictive on time constraints or restocking fees I would rather not make a costly error or discover a dye lot is no longer available.

    Anyone else have this concern and how did you address it?

    Thanks to all and Happy New Year

    Weather Underground is a wonderful website to use if you need to catch up on the days in the new year. They archive the highs and lows everyday in a user friendly calender. Happy crafting, friends!

    I live in San Francisco and there isn't that much of a temperature variation here. I'm looking at those colors and I think my blanket would basically come out to be all green shades.

    How many stitches would I cast on? I love this idea, but I'm a real pattern follower.

    Do you use the days high temp, low temp?

    I plan on trying this with a corner-to-corner blanket (crochet). Since it makes a square, I feel that this would ensure that I don't have to worry about how many to chain to start off the blanket, and end up with something that's not very wide, but VERY long.

    If you keep increasing through day 183, and then start decreasing for another 182 days, you'll have 182 rows on either side of the "longest" row, creating a nice even blanket. I tried to find a Lion Brand corner-to-corner pattern to paste a link to here, but didn't find a basic one. If you do a google search or are on Ravelry, you could probably find one pretty quickly, if you've never tried the c2c technique before. Happy crafting!
