I designed the Koru Geese Block many years ago as a template to make a Temperature Quilt. The pattern has been updated a couple of times and assumes that the sewer knows how to paper piece and also understands how to make a Temperature Quilt.
So what is a Temperature Quilt?
Temperature quilts are a record of daily temperature high's and low's that occurred throughout a single year, in a particular place. Usually from 1 January to 31 December. The record is like a daily diary 'written' in fabric and colour, not words. Making your own temperature quilt can be a fun and creative way to track the weather and the changing seasons. Generally, two temperatures are recorded on a daily basis - a high and a low. The high temperature is usually in the middle of the day and the low is usually overnight. In terms of fabric colour, you might use blue fabric to represent cold temperatures and red fabric to represent hot temperatures. You then create a scale of fabrics between red and blue, that correspond with temperatures. This scale will be your reference to determine which colours you use.
While temperature quilts generally record the current year, you could also use a website like wunderground.com to gather historical data to make a quilt as a gift using a special birth year or anniversary.
One of the shortcomings of the Koru Geese Block pattern is that it doesn't provide any information on choosing fabrics or using a temperature scale. Part of the reason I didn't include this information is that the pattern isn't only for temperature quilts. You can use the pattern by incorporating it into pillows, tote bags, pouches or use it to explore colours and patterns in other ways, for example, a rainbow quilt, or other quilts. There are some ideas at the end of this post.
I thought it would be helpful to give you all the details of my temperature quilt to help guide you in making some decisions with your own temperature quilt, along with ideas from other designers.
Do a little research first
One of the first things I did before gathering my fabrics, was to ask myself:
Do I want to record a region; state; city or suburb? In order to answer that I did a some research into the historical temperature ranges recorded locally and in the wider region that I live. I quickly realised that I didn't want to record the city wide high's and low's as there was some variation from north to south. The temperatures locally - within my suburb - tracked a little higher during the day and a little lower over night. I decided that I wanted a record of the temperatures I had experienced on a day to day basis, so local it was. If your local temperature isn't available, you might need to broaden your temperature area to city-wide. If you have the ability to measure your local temperature yourself, this could be an interesting option too. I found the micro climate comparisons quite interesting. The Koru Geese Pattern works best when two temperatures are recorded. I chose to record the day time high and the following overnight low.
My next big question was:
How many degrees of temperature would I include in my scale? In Auckland, we have a narrow range in temperatures and we use Degrees Celsius to measure temperature. The graph to the right gives an example of average Auckland temperatures. I was able to easily assign one fabric colour to each degree. In hind sight I would have assigned my daytime highs from 12°C to 28°C and my overnight low temperatures from 2°C to 21°C. Bear in mind that if you use a table like the one to the right, which shows average temperatures, the temperatures you actually record are likely to fall above and below those on the graph.
If you measure and record temperatures in Fahrenheit, it will be easier to use temperature ranges. The images below show the temperature ranges by www.darcyquilts.com. She used 4°F increments so she could use more fabrics. Depending on the temperature range where you live, you could use 5°F or 10°F increments.
Things to Consider
I recommend having a plan for what you'll do if your temperatures fall outside your temperature range. I made the decision to assign my daytime highest temperature fabric to 27°C and above and the lowest to 13°C and below. I did the same with my overnight low fabrics. The downside of this was that we had a hot summer and days where the highs and the (highest of the) lows ended up being the same colours over several days. Once the quilt is finished it won't matter though. It will still be a great representation of the change in temperature throughout the year. And no one will really know what the actual temperatures were, not even me!
Something else to consider is whether you'll use a single set of fabrics for your temperature ranges (like www.darcyquilts.com has done) or if you will split them - as I have done - into daytime highs and overnight lows. I graduated my fabrics from red for hot, to blue for cold. I used Kona Solids for the daytime temperatures and I used Essex linens for the overnight lows. Some of my Essex linens have a shimmer and some without, this offers some movement and variation throughout the quilt. Using different fabrics for the 'geese' of the Koru Geese block allows them to pop out of the block more.
Solid fabrics are an obvious choice, however, I’ve seen batiks and blenders used with success. If you decide to use two sets of fabric ranges, you will need almost twice the number of fabrics. Download my Temperature Quilt Template which includes two blank templates for you to use along with my own template which you can use for inspiration and reference.
The picture below right, shows a Temperature Quilt Range and Colour reference from www.elmstreetquilts.com using 10°F increments.
Make sure you have somewhere to write down your temperatures each day. This is important both for when you can't get to your quilt each day and when you're out of town or on holiday and need to record temperatures for easy reference later. I quickly realised that my suburb temperatures were not easy to find a day or two later. City temperatures are easy to find historical data on, suburbs are not so easy. Find a website you're happy navigating around, bookmark it and refer back to it when needed. It became a evening routine to jot down the previous overnight low and daytime high. I happen to use a paper diary and also happened to have some monthly sticker which I found useful for recording my temperatures. Something to note is that you don't necessarily need a calendar that shows days, months and the year. A perpetual calendar will do. Simply note the name of the month (and year if you wish) on each month so you can keep them in order.
Using the Koru Geese Block Templates
The following instructions assume you will be using daytime highs and overnight lows. If you've chosen a different way of representing your temperatures, you will still find these instructions useful.
You'll need four templates from the Koru Geese Block pattern to make one complete block - which represents one month of temperatures. There are 32 'geese' (triangles) on each completed block. This was the logical solution to create an even looking block, but does mean that some 'geese' at the end of the month will not be used. How you paper piece these final pieces is up to you. I chose to continue using the last fabric to complete the block.
The 1st of the month starts with the daytime high temperature on 1 (on the template) followed by the overnight low on both 2 and 3.
The daytime high for the 2nd day of the month is sewn on 4, with the overnight low sewn on 5 and 6.
The daytime high for the 3rd day of the month is sewn on 7, with the overnight low sewn on 8 and 9.
And so on.
Writing the temperatures on the template before starting does make it easier to keep track of where you're at while sewing. I generally waited until I had 8 days of temperatures before completing one quarter of the finished block. You can sew a 'geese' each day if you wish. I also recommend writing the month on the template too and leaving the paper templates on your blocks until you are ready to sew your finished quilt together. This way you won't be wondering which month is which!
Completing your Blocks and Quilt
Once you have four completed templates (one month), sew the templates together as described below and and shown in Fig. 1.
1. Place your four completed templates on your work surface and rotate each block so that a circular shape is created.
2. Sew Row 1. Place two templates RST, sew with a 1/4" seam allowance. Press the seam to the right.
3. Sew Row 2. Place two templates RST, sew with a 1/4" seam allowance. Press the seam to the left.
4. Sew Row 1 and 2 together. Place RST, nest seams and sew with a 1/4" seam allowance. Press seam open.
The final seam is pretty bulky, so take is slowly.
Now that you have your blocks sewn together, it's time to decide how you will sew them together into a finished quilt. Here are some ideas!
Sewing the Koru Geese Blocks together with no sashing will result in a quilt like the one to the right. These is some space between each flying geese circle to allow them to stand out individually. This quilt will measure 36" x 48" which is a pretty small quilt, ideal as a wall hanging or baby quilt.
If you are looking to make a larger quilt, or you'd like to avoid those bulky seams, adding sashing is a good option. The image to the left shows the Koru Geese Blocks sewn with 2½" sashing strips, which once sewn together will be 2" wide. This quilt will measure 44" x 58" which would be a small lap size quilt. Additional or wider sashing could be added to make the finished quilt bigger.
If you're not making a temperature quilt, additional blocks and sashing could be added to make an even larger sized quilt.
