Temperature blanket – the perfect baby gift

In 2017, I started crocheting temperature data. It was inspired by a tweet I saw on Twitter at the very beginning of that year of a temperature blanket the size of a bed comforter, and I’ve had an incredible amount of fun scouring the NOAA records for daily maximum temperature data to use. I’ve made items that include a scarf made from a year of data following the first day of work for an administrator at my campus, to semester-long mini-tapestries separated by 50 years of data to show my students as the semester progressed. I crocheted a temperature tapestry representing the temperature record starting at the establishment of a local arboretum (see summary). And I’ve even presented about these crocheted temperature examples at an American Geophysical Union (AGU) Fall Meeting (see summary).

But my latest focus of crocheting temperature data – creating a temperature blanket as a baby gift.

Temperature blanket for a baby born in August 2020, capturing the daily maximum temperature for the first three months of his life.

It is very simple to do. Once the baby is born, I can look online to see what the daytime high temperature was, and each day add a new row to my blanket. After three months, I have a very personalized baby blanket as a gift! Granted, the gift is then three months late (after the baby is born), and I have to guess what the range of temperatures might be to establish the yarn color scheme from the start, but it is worth this when the reaction comes in from the newborn’s parents.

I’ve created another blog post as to how and where to find temperature data, especially if the baby is not born in your local area. And there are no rules that say you have to crochet a row each day – one can certainly wait until after the first three months have concluded to determine the colors to use with the temperatures. And there is also no expectation to use the rainbow colors – red for warm temperatures, and blue/purple for cooler temps. I’ve actually been criticzed for using the ROYGBIV scale, as it can be difficult for those with varying degrees of color blindness to see the difference across the scale. I encourage you to use which colors you feel comfortable with (and which colors you have in your collection and available to use!). I’ve been a fan of using the super bulky [6] Bernat Blanket yarn (regular, Baby, Brights) for my rainbow effect.

When I gift the blanket, I also include a description of what the blanket shows, a graph of the temperature data plotted, and some facts about what happened with temperature during the first three months. For example, for the blanket pictured in this post, below is the graph and random facts I included with the gift.

I should note that I focus on daily weather data, not how much the temperature varies from the climate record for that date. Having the blanket share climate data would have it look like something you would see in the climate warming stripes graphic – an all-red blanket, and a reminder that the baby was born into a warming world. Temperature data is much more friendly and less anxious when it stands alone.

This handmade gift is then shared by the parents with family and friends – in essence, I am also turning the parents into science communicators, getting them to think about the changing temperature in the world around them and how it has changed in such the short time of their newborn’s life. I don’t know the long-term impact of the temperature baby blanket – does the family talk about what the colors mean in the blanket with the kid when they get older? Does the family keep the blanket? At least, for the short-term, I know the blanket brings joy and a little bit of science to the lives of the family.

I leave the ends of the rows as fringe, as there can be alot of color/yarn changes in just three months to work in the blanket!

Such a sad-looking, dry rain garden. I hope it’s ready for when the rain comes back!
This phone is no longer welcome on the second floor of our house (where the two rooms have now been converted to home offices). There’s way too many spam calls during the day, and it’s conference presentation season (ACS & others...)
We found a hidden gem today (Best of Philly's Most Overlooked Tourist Attraction!). If you are looking for a spot to learn some more U.S. history that is outdoors and plenty of space to socially/physically distance, you'll want to check out Fort Mifflin. On the Delaware and right next to the PHL airport, this National Historic Landmark is the only fort in Philadelphia and was first built in 1771 by the British to protect Philadelphia. I never knew we had a "Pennsylvania Navy" flag (which still flies above the fort). Bring a picnic lunch, bring your binoculars for wonderful bird/wildlife viewing, and wear boots/shoes you don't mind getting a little wet (it is called Mud Island for a reason...).
Excited to start the fall semester as a Faculty Athletic Representative to the @psubrandywine Women’s Volleyball team! Volleyball was an important part of my high school years (pictured here as co-captain of the Plainville High School Blue Devils, number 12) and undergrad/graduate years with intramurals and pick-up games. Looking forward to connecting with the coach & players soon & supporting @psubwsports student athletes
To connect with the new Drawdown DCIS series at the Delaware County Institute of Science, each month I'll be creating a mini-quilt for my front door that celebrates the sectors of climate solutions from @ProjectDrawdown and the topic from that month's DCIS lecture.
