How I’m Planning My Temperature Quilt

I’ve admired temperature quilts from afar for years.

The gradients. The slow build. The way one quilt can quietly document an entire year of life in fabric. It’s such a cool concept, and also exactly the kind of project that can make your brain go, “Wow, that sounds amazing. Anyway, let’s start something easier.”

But after a little nudge from Brendan, also known as Mister Quilter, I finally decided this is the year.

Watching Brendan start his first temperature quilt reminded me that these projects do not have to be perfect or overly precious. They just need a plan, a little curiosity, and a willingness to keep showing up one day at a time.

So here we are.

In this post, I’m walking through how I planned my temperature quilt, including my color palette, temperature key, layout, and the free planning resource I created to make the whole thing feel less intimidating.

Listen to the Podcast Episode

I also recorded a podcast episode about this project, where I talk more about how it started, the decisions I made, and what I’m hoping this quilt becomes over the next year.

What Is a Temperature Quilt?

A temperature quilt is a year-long quilting project that uses fabric colors to represent the daily temperature.

Most quilters choose a range of colors, assign each color to a temperature range, then sew one block, unit, or piece for each day of the year. Some people track daily highs. Some track daily lows. Some use the average temperature. Some use two colors per day to show both the high and low.

There’s a lot of room to make it your own, which is both the magic and the tiny trap door.

Because yes, the options are endless.

And yes, that means it helps to make a few decisions before you begin.

Starting With Fabric: A 16-Color Gradient

The first thing I did was pull fabric from my stash.

I knew I wanted a clear, readable gradient, so I started arranging solids from coldest to warmest until I landed on 16 fabrics that felt balanced and expressive without being overwhelming.

All of the fabrics I’m using are Pure Solids from Art Gallery Fabrics, and they are available in the Quiltbound shop.

Most temperature quilts use somewhere between 10 and 20 fabrics, depending on:

• The pattern or block style
• The overall quilt size
• How much variation you want to see
• What you already have in your stash

Sixteen felt like the sweet spot for me. It gives the quilt enough nuance to show seasonal shifts, but not so many colors that the whole thing starts feeling like a spreadsheet wearing a costume.

Researching Historic Temperatures Before Choosing Ranges

Before assigning temperature ranges to my fabrics, I looked up historic weather data for Castle Rock, Colorado.

Historically, temperatures here have ranged from about -27°F on the cold end to 102°F on the warm end.

That is a huge spread.

Knowing those extremes upfront helped me avoid one of the most common temperature quilt problems: choosing a beautiful palette, getting halfway through the year, and then realizing the weather has gone fully feral and you do not have a color for it.

Planning for the extremes gave me a temperature key that can actually support a full year of data.

Creating the Temperature Key

Once I knew my full temperature range and had my 16 fabrics laid out, I built my temperature key.

Here’s the thing that made the biggest difference: not all of my temperature ranges are the same size.

That was intentional.

Why I Used Uneven Temperature Ranges

Extreme cold and extreme heat do not happen very often where I live.

Middle-range temperatures happen constantly.

If I divided every range evenly, most of my quilt would land in just a few middle colors. That would still work, but I wanted more visible color movement throughout the year.

So I used wider ranges for the extreme highs and lows, and narrower ranges through the middle temperatures.

This helps create:

• More color changes during the most common weather
• Clear visual markers for unusual temperature days
• A quilt that feels more interesting over time

It’s a small planning decision, but I feel like it will make a big difference once I’m 200 days into this project and questioning every choice I’ve ever made. As one does.

My Color Palette and Temperature Key

Here’s the full temperature key I’m using for my quilt, listed from coldest to warmest.

Temperature Range	Fabric Color
-40°F to -20°F	Crème de la Crème
-19°F to -5°F	Bewitched
-4°F to 10°F	Nocturnal
11°F to 20°F	Nova
21°F to 30°F	Evergreen
31°F to 40°F	Spruce
41°F to 45°F	Eucalyptus
46°F to 49°F	Garden Fern
50°F to 54°F	Aurus
55°F to 60°F	Honey
61°F to 68°F	Raw Gold
69°F to 75°F	Apple Cider
76°F to 82°F	Chocolate
83°F to 88°F	Terracotta Tile
89°F to 95°F	Aurora Red
96°F to 105°F	Candied Cherry

This palette moves from cool neutrals and deep greens into warm golds, rusts, and reds.

Very “four seasons, Colorado edition.”

Planning It All on Paper

Once I had my palette and temperature key, I knew I did not want to keep all of this straight in my head for an entire year.

Memory is a liar. Especially when fabric colors, daily temperatures, and long-term projects are involved.

So I created a Temperature Quilt Planner, and then decided to make it a free download for anyone else planning a temperature quilt.

The planner includes:

• Space to plan your color palette
• A temperature key
• A 365-day temperature tracking chart, plus space for leap years
• Room to track daily highs, lows, or averages

It’s designed to live next to your sewing space and turn temperature tracking into a simple daily ritual instead of one more thing your brain has to carry around.

My Quilt Layout: Highs and Lows with Half-Square Triangles

For the quilt design itself, I’m using a mix of large and small half-square triangles.

Each half-square triangle represents one day.

One half of the HST represents the daily low.

The other half represents the daily high.

I love this approach because it captures the difference between day and night, while still keeping the piecing simple and repeatable.

The color does most of the storytelling, and the HSTs add just enough movement to keep the layout interesting.

That mattered to me because this is a year-long project. I wanted something I could return to again and again without needing to relearn the whole thing every time I sat down to sew.

Simple structure. Slow story. Big payoff.

Why Temperature Quilts Are Worth Making

Temperature quilts are technically about the weather.

But also, they are not really about the weather.

They’re about noticing.

Noticing the seasons shifting. Noticing the weird warm day in February. Noticing the cold snap you forgot about until it shows up as a dark little patch in your quilt.

They’re about marking time in a way that feels slow and tangible.

By the end of the year, this quilt will hold the shape of ordinary days. The school drop-offs, sewing sessions, errands, coffee refills, podcast episodes, workdays, snow days, heat waves, and tiny moments that don’t always feel memorable while you’re living them.

That’s the part I love most.

A temperature quilt turns a year into something you can hold.

Want to Make Your Own Temperature Quilt?

If you’ve ever wanted to make a temperature quilt, consider this your permission slip to start imperfectly.

You do not need the perfect palette. You do not need the perfect layout. You do not need to know exactly how motivated you’ll feel in July.

You just need a plan that supports you.

Start with your location. Look up your historic temperature range. Choose colors you actually want to sew with for a whole year. Decide whether you want to track highs, lows, averages, or a combination.

Then make it easy to keep going.

One color at a time.

One block at a time.

One little weather-fueled quilting side quest at a time.
