data visualization with embroidery

An introduction

  • Embroidery as a secular art and domestic activity began in 17th cen. Europe, primarily in England.
  • Previously, it had been limited to ecclesiastical and courtly attire.
  • It became a popular hobby for women of all social classes in the 18th cen.

An early example

The Bayeux Tapestry

Noble attire

Tudor blackwork embroidery

A set down

Dr. Sloper: A hundred women are prettier, a thousand more clever, but you have one virtue that outshines them all.
Catherine: What, what is that?
Dr. Sloper: Your money!
Catherine: Father!
Dr. Sloper: You have nothing else.
Catherine: Oh, what a terrible thing to say to me.
Dr. Sloper: I don’t expect you to believe that. I’ve known you all my life, and I’ve yet to see you learn anything. With one exception, my dear. You embroider neatly.

A domestic art

Embroidery was for a very long time a set of practices that oppressed women. But you can find examples in almost every culture of women who found in embroidery itself, a way of subverting that oppression. Who found a way of escape, of creating, of protesting, a way of sharing, of collectively creating, of even having an economic advantage through embroidery.

A metaphor for human connectivity

Loaded with gender connotations and power hierarchies, fiber and textile traditions [… ] provide a fitting platform for examining tastes, roles, and relationships socialized within and around gay and lesbian culture. And thread—be it yarn or embroidery floss—parallels the potential for connectivity in our lives as same-gender-loving and gender-non-conforming peoples. Our commonalities may be as thick as a knot or as thin as a string. As individuals, we are strands; as communities we are interwoven. Both can be broken or braided.

A site of resistance

I wanted to stab someone 8000 times. Instead, I cross-stitched an ancient design.

Textile Arts and Political Activism

A few examples, past and present.

Major Casdagli in WWII

Alexis Casadagli’s work

Morse code

Steganography

The word ‘steganography’ refers to the act of concealing secret information within something public, in order to avoid detection. In other words, hiding something in plain sight.

What can be data in textiles?

Anything you care about, really. A few ideas:

  • Data from wearables
  • The scansion of a favorite poem
  • The plants in your yard
  • The character and quantity of your laughter (see Dear Data for more fun examples)

Symbols as data

Dina Van Bergh’s wedding dress, SCUA

Quilt patterns (or myths about them) as data

  • “Isn’t it true that Log Cabin quilts with black centers were hung on the clothesline during the days of slavery to alert escaping slaves to the presence of a ‘safe house’?”
  • “Were quilts read as maps to tell escaping slaves the route to safety?”
  • “Is a pattern known as”Friendship” or “Mother’s Oddity” a secret code for Lesbianism?”

Log Cabin Pattern

Double Ax (Mother’s Oddity)

Double Ax Head quilt, ca. 1890s

Embroidered data: some examples

A geometric blackwork pattern, interrupted

Example 2

embroidery inspired by a spectrogram of a 52-hertz whale

Data Assembly

Moving from data collection to data transformation.

Data Transformation 3

I wanted to create a design that is 9 shapes across, instead of 10, so I reconfigured my two variables to be a proportion of 9.

(raw number / maximum possible raw number) * 9

Data Transformation, in sum

  • Transforming raw counts to proportions is a great help
  • Precision is not required :)

Planning your design 3

Planning your design, in sum

  • Sketch your ideas first with colored pencils
  • Graph paper helps for precision
  • It is MUCH easier to follow your plan while embroidering rather than developing that plan and stitching at the same time

Activity 1

Reflect and sketch: Sketch out your data idea on the provided graph paper. Need inspiration? Consider:

  • What do you care about? What do you value?
  • What kinds of stuff can you access?
  • What would be needed to transform the stuff you care about into (stitchable) data?
  • What questions does this activity raise for you?

Embroidery basics

Materials

  • embroidery threads
  • base cloth
  • hoops or frames
  • transfer pencils/pens
  • scissors

Techniques

  • drawing directly on the fabric
  • tracing
  • transfer paper

Stitches

Running stitch
  • Thread needle and tie a knot at one end. Bring needle up from the back until the knot hits the fabric.
  • Insert tip of needle one space away from where you came up and “load” the needle by going in and out of fabric to create series of stitches.
  • Repeat as necessary. Finish by tying a knot underneath—make a loop and pass the needle through the hole, pulling tight.

Stitch directories

Activity 2

Let’s use the fabric pen to trace your design (or a grid to support it). And start stitching!

Project idea

Enter a project into the Big Ten Academic Alliance’s Love Data Week Data Visualization Championship! Students should use the NCAA Women’s Basketball data. Faculty and staff can use any data from their own research or BTAA-related. The winner last year of the faculty/staff entry produced a quilt, so handmade, physical objects are welcomed!

Thanks

That was a lot. Let me know if it would be fun to work on your embroidery collectively in person or online!
