Binche/Flanders tension solutions

My previous post started a discussion on Arachne about using additional support pins and other thechniques. I made a working diagram out of Susan Roberts’ description. I also like Clay Blackwell’s idea of nail polish for the insect pins used as additional support pins.

On the left the usual working diagram of an “insmijting“, the LOKK suggest a ctctc for the orange stitch, on the right how Susan Roberts learned it from Anne-Marie Verbeke-Billiet.

Challenge

Bored with winding bobbins I looked for a challenge and stumbled on the “Binche compact” sampler, designed (assembled from other patterns) by Hildegund Jene for the German lace guild, the DKV. Somebody told me being able to read a color coded diagram would allow me to recreate it. When the pattern arrived it said to require experience with Flanders Paris and Valencienes lace. I only had some experience with Flanders, so I got my challenge. Along the edge it is not the complexity but the larger cloth stitch areas with pairs changing direction without a pin for support that created a real tension problem. I must admit I’m a puller. So I decided to to continue a while longer with the ringed snow flakes (Ulrike’s “Viele gute Grunde” might provide a variation) and  reuse an earlier corner to tie off prematurely.

Now I have another challenge:

Somehow fill in the gaps along the corner in a more or less symmetric way. Where the picots change into a straight edge, there are three additional pairs to get rid of, perhaps I should replace the last outer snowflake. Suggestions and warnings would be welcome.

A consequence of not undoing too much will be one edge with picots and three without. But its a sampler after all, so why not?

binche-hoekUpdate 1:

A first sketch shows it are only two pairs to get rid of. But it is definitely not wining any beauty contest.

Update 2:

Susan Roberts hinted me to remove some more of the original pattern. So a new sheet of transparent paper with removable tape on a new print. It is going better now. But I need to remove more on the bottom right. On the left I could use pairs as threads to make a pair disappear in the spider.

added-pair

On the right an upside down scan of how the pair was added. Something like that could also be an idea, weave one thread through the ring pair, a half knot with itself makes a double twist and weave it back into the spider to double its sibling. To be continued…

Update 3:

Reread Susan’s message, she thought more “bolletjes” might fit. Indeed they did. The two pairs to get rid of can meet in the spider. Once the puzzle is cracked it looks so simple.

Update 4:

As pairs going up takes seasoned Binche lace makers completely out of their habits and rhythm another version. The smudges show it did not came easily, and I’m still not sure I got everything right.

Math and lace II

June 26, 2016 at 1:39 pm | Posted in Uncategorized | Leave a comment

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 TesseLace.com), 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?

Ronde Rasters

Er zijn vele polaire rasters in de omloop, maar bij de meeste traditionele vormen hebben de slagen aan de binnenkant een andere vorm dan aan de buitenkant.

rasters

De rechter variant is sinds kort op twee manieren beschikbaar (zonder de lijntjes, die zijn toegevoegd om te benadrukken dat de vierkantjes aan binnen- en buitenkant even vierkant zijn):

  • Maak op een web pagina je keuze in variant en afmetingen, selecteer via afdruk-voorbeeld de pagina met het raster en druk deze af. Meer heeft het niet om het lijf. Druk je af in landschapsformaat, dan kan de marge het volledige adres van de pagina bevatten, daarin staan de keuzes die je gemaakt hebt voor als je hetzelfde nog eens wilt afdrukken. Met een verkeerd aantal stippen per ring kan rechts een onreglmatigheid ontstaan. Geen probleem voor een waaier, maar probeer het anders even uit tot het klopt.
  • Om een raster op de computer verder te bewerken is er een InkScape plugin varinat. InkScape is een gratis programma. Met deze variant kun je ook rasters met verschillende dichtheden combineren, een beetje zoals linksboven. Niet door mijzelf getest maar waarschijnlijk kun je een raster met InkScape gemaakt ook met Adobe Illustrator verder bewerken. Ik hoor het graag als iemand dit kan bevestigen of tegen spreken.

De pagina’s zijn in het Engels, ik wil een zo breed mogelijk publiek bereiken en ga graag door met andere software voor het kantklossen. Wil je helpen met een vertaling dan kan dat natuurlijk.

Wikisapecs announced the termination of their free plans. K12 nor higher education applies to the bobbin-lace space. So far few* contributed to the wiki which was intended to be a collaborative effort, so I do not consider to pay $5 per month to keep it alive, my effort alone should be more than enough contribution for the lace making community at large.

Short before the dead line I discovered between the discussions… it absolutely does not need to be initiated or used within a school to qualify. Home schooling, or a presentation wiki created by a teacher giving a talk at an education conference are two examples of wikis used outside of schools that qualify.” Only small changes were required to reduce the focus on learning making bobbin lace. Meanwhile wikispaces approved my request to continue the bobbin lace space.

So celebrate with me and please clean up the grammar in my changes of the last few weeks.

Two previous posts where about a three pair star. The French call it the “fond Malin”, dentelle-et-papillon shows two methods. Somewhere I saw online instructions for four, six and eight pairs. Now I can only find this example of eight pairs. Anyone who knows to locate the instructions?

PS: Ulrike Löhr has examples in her book Handbuch mit 400 Tricks und Kniffen.

for seasons trees

Made these trees years ago, pattern by Lenka Suchanek

versieringen

chestnuts for autumn and blossoms for spring

I never got around to frame the four trees and show them prominently. This week I found a nice 3D idea between glass sheets by Mechel Ensing. The challenge: How to overcome the thick trunks and weight of the eight sheets of glass. Any ideas?

The pattern was originally published in 1983 by Lenka Suchanek for personal use. Teativität shows how Lenka instructed to do the trunk. Some tend to attach the fringes later. Whatever method you choose, don’t use an edge pair on the inside: It creates an even stiffer less natural result.

The images below link to other shapes of the tree and my variant of the instructions with specified lengths to use left overs.
