A few improvements

First, I was asked to add a some keyboard shorcuts to the grid tool. It’s now much more efficient if you use a lot the selection tools.


I also added some visual helps to the realistic tool.

On the left threading description, a red line show the middle of the band.


In the display panel, there are two new options.


First the ability to show row numbers. 

In fact, this option not only show row numbers but also heddle thread number.

With the «vertical guide» option you can add vertical lines to you pattern display. You can choose between no line, just a line on the middle or a red line on the middle and a blue line every 4 thread.


Last modification, on the weaving ruler you now have information of the picks, drops and dual colors of the previous row.

Here :

  • the dual color is used for heddle threads 2,3, 11, 21, 29 and 30
  • on the previous row, it was the open threads 3, 4, 7, 11 etc
  • the thread between heddle threads 5 and 6 is picked up
  • the heddle thread 7 was picked up during the previous row.

Stoorstalka heddles

Seizenn offers facilities for creating patterns for stoorstalka rigid heddles.

The pattern presented here are mainly taken from the stoorstalka sets available on the site https://shop.stoorstalka.com/en/products/handicrafting-diy/yarn/weaving/

We first choose a common color palette for the Nordic patterns. In the palette creation tool , let choose palette “30”.

Then we will open the tool for “realistic” patterns


In the left menu, go to the “load, Save, Export” submenu. There is a drop-down list with the different heddle models. Just choose a pattern and click on the “heddle pattern” button.

The models available are basic, sigga and sunna. By default the models use the first colors of the palette.

Basic Pattern

Basic heddle is for simple plain weave band. 4 size are available corresponding to the total number of threads : 31, 63, 103, 131.

For “basic 31” you get this default pattern.

You can then modify it to get, for exemple (beginner-level-1/weavekit-basic-vardag-red) ,

Sigga Pattern

Sigga heddle are for dual color float pattern. There are three sizes , 8, 16, 24, corresponding to the number of floating threads.

The Sigga 8 default pattern looks like  

You note that there are 8 green dual color floating thread. Pattern is 35 threads wide and 8 threads have dual colors.

Using the dual color mode and the pickup mode you can get a pattern like (https://woolery.com/stoorstalka-band-weaving-kit-advanced.html)


Sunna heddle is for pickup pattern (baltic). 4 sizes are available, 5, 7, 9, 13 corresponding to the number of pickup dots, the width of the pattern. Sunna 5 pattern has a total of 37 threads.

The Sunna 5 default pattern in seizenn is

You can modify it according to https://shop.stoorstalka.com/en/products/handicrafting-diy/yarn/weaving/band-weaving-kit/professional-level-3/weavekit-professional-yellow-red.html  using the pickup tool.

You could also use the grid tool to create you pattern


This is a personnal project using Sunna 13 heddle. I didn’t use all the border holes.

Starting from default Sunna 5 pattern, you can do this in Seizenn by removing threads and using arrow buttons to move threads and patterns.
