Knitting workshop during ArcInTex at TU/e Eindhoven

During ArcInTex  week on last Thursday there were informal workshop sessions at the wearable sensor lab of TU/e Eindhoven. Organizers were Dr. Tomico Plasencia, Marina Toeters and others.

My theme for one of these workshops was based on knitting experiments reported in this blog. The idea was to have a small group of participants experimenting on coding in knitting, in the line of this “from GPS to knitting” post.

To make everyone knitting on knittings machines without any introduction is a bit too much to ask for one afternoon, so I brought these Quick Knitting wheels. The challenge for the participants was to find out how to make a bend in the circular knitted tube which you can easily produce with these wheels.

The organizers quickly added a Silver Reed and a PASSAP knitting machine. The Silver Reed was extensively tried out by students from MICA Baltimore which were visiting the school where I teach (, and were also present at Eindhoven.


Also several circular hand knitting devices appeared out of nowhere:


circ6  circ5 circ4  circ3 circ2  circ1

The cbending hallenge was solved by several participants, here an “educational” example: (Troy made this)


While another participant made what even looked like a “glove”: (by decreasing to one peg, you get a point like bend)


This challenge was given with the designed GPS track in mind, when done in circular knitting this line requires bends to the right and to the left.

track-90 Figure: bends to the left and right are required for a 2D tube version of this track.

Starting real bending:

bend_1 bend_2 bend_3 Inserting yellow (thicker) thread between the grey threads to make a smooth bend. Half the ring was used for the yellow thread and then a whole ring of grey. Around 15 inserting tours of yellow was needed to make the corner. Because this depends on the thickness of the thread, a test bend is always needed to find out this number.

The double bed knitting machine can make “socks” and a bend to one side can be made ( but for the knitted GPS track “in 3D” we need also the other side bend, which on the knitting machine requires that you get the knitting of the bed, reverse it and knit the second bend – or so it seems…further research has to be done.

With the circular wheels you can increase and decrease at both sides without a problem, because it is done by hand anyway.
