A lot of water went under the bridge since the previous article, didn’t use Voronoi-Delaunay diagrams after all but force directed graphs. The diagram generator left the proof of concept stage that just showed just a few stitches without anything choose. Now you can select a pattern resulting from Ph.D. research by Veronika Irvine (see, and choose stitches and thread colors to get even more variations. The generator gives you matching pair and thread diagrams.


Proof of concept

Nothing to install, just play with a web form. The work is still not done as the generator still has its problems generating thread diagrams for some of the patterns.

The Voronoi-Delaunay diagram reminds how the DiBL ground generator builds on a paper by Veronika Irvine. She generates tons of variations of graphs as illustrated with the networks of connected dots. Then I jump in with DiBL to draw stitches on the cells or tiles. Thread diagrams help to study the effect of variations in color or thread size, corresponding color coded diagrams help to create the actual lace.

The diagram editor is built with the same JavaScript library as the Voronoi-Delauny diagrams. These are just two of various inspiring finds. Sad there are way too few hours in a day to get things to a next level for bobbin lace. Really need more (wo)man-power. Any volunteers interested?

result with double wire of 0,1 mm (38 gauge)

The element could also be used as a charm or pendant, or chain them 3×3 together to follow a recent trend. With beads attached youre fingers hardly feel the cut off ends. However, the clumsy way I attached the beads doesn’t marry well with a knit rollneck. With thick wire the element might reach a scale for a wind chime.

Inspiration came from a background motive in “Tribute to the first people” designed by Anny Noben-Slegers. It appeared to be one of the variants of B7a from “Viele gute Gründe” of Ulrike Löhr.

With and height are not identical, therefore two diagrams. Choose your own spider or snowflake in the gaps of the diagrams. Reduce the pattern depending on the size of the used yarn or wire and your skills to work with wire.

Wire lace with insect pins

necklace clasp part with five droplets Via inheritance (with a warm hand) I received a clasp part of a coral necklace. I don’t like the idea to wear it like my mother used to do, so I did not know what to do with it for a long time. Recently I discovered copper wire of 0.06 mm (42 gauge) thin. Originally meant to wind spools for microphones. The images show an attempt created with doubled wire and wild ground.

Wild ground means: one by one a single and double half stitch with just an insect pin to support the edge. To create the eyelet I ended with four pairs: a cloth stitch with pairs as threads, two plaits and where they meet again a cloth stitch with pairs as threads. On the way back, sew the plaits halfway around the first plaits.
