A few improvement for the SeiZenn inkle tool.
I was asked about the possibility of adding a thread inside a pattern. Until now it was only possible to add new threads to the right of the pattern with “width” parameter
So we had to play with the buttons
to be able to add the thread in the right place.
It is now possible to right-click to add or remove one or two threads where you want in the pattern.
This function takes into account the “symetry” option.
Joan Sheridan explains in this video (https://www.youtube.com/watch?v=xtAxaL0S8BU) how to do turned Krokbragd on the inkle loom.
That kind of pattern can be done in SeiZenn with duals
I added some functions to make it easier to create this type of pattern. From a pattern,
add a double color on the bottom row with “dual half threads” button
we obtain (it uses the selected color for all the duals) :
You must then indicate that you use the double color every other row. Rather than doing it by hand by clicking on the lines concerned, you can use
You can then adjust dual colors as you like
I slightly improved the function for generating a threading document which was accessible with the button “create instruction note” in the “load, save, export” menu
Now this button generates a PDF document.
(in this example, you need to verify the grid start and end values to be able to see the grid view)
during summer I built two new looms.
First, a new stand for tablet weaving. It looks like the one on page https://www.raktres.net/blog/2022/08/10/tissage-aux-cartes/
The second is a bit more complex. It is a vertical loom with 4-shaft for baltic bands.
I added a simple tool to draw tablet weaving pattern : https://www.raktres.net/seizenn/#/tablet. Here is a post to demonstrate how it works for double-faced patterns.
First, in the main menu of seizen open the «tablet weaving tool». It works the same way other Seizenn tools.
On the left menu, in the “Load, Save, Export” menu, you can choose the size of your pattern and click on the “create” button
As you want to create a “double faced” pattern, in the “tools” menu, choose a “Double-faced” threading and a “2+2” rotations (repetition of 2 fronts and 2 backs)
You now have a blank pattern, ready to draw on it.
Like with the other seizenn pages, the colors are selected from the color palette. Default threading use the 2 first colors. You can of course change them.
On the “Edit Mode” menu, choose “double-faced mode”
Now, when you click on the pattern, you flip two cases, as required to draw a double-faced pattern. You can change the weft color by left clicking on the down left square with the wanted color selected.
If you click on the first row, it will change the hole which is upside at the begin. Useful for standard tablet-weaving. Maybe less for double-faced pattern.
You also can do some actions depending on where you right clicks (add cards or pick, change twining etc.).
GTT is a very great tool, and many patterns made with it are available. You can find some on http://www.guntram.co.za/tabletweaving/patterns/df_heraldic.html
On the “Load, Save, Export” menu you can load GTT file. (GTT is very powerfull, not all kind of pattern can be read with Seizenn)
If you choose the wolf :
Watch out, Seizenn doesn’t use the colors from the pattern file. I made this choice because you may not have in your shelves (in your main and loom palettes) exactly the colors that was used by the person who created the pattern. And colors are very simple to change with Seizenn.
If you want to work with square pattern, show rotation changes, turning etc, choose the optinos in the «Display option» menu. You can get for example :
The Sulawesi tool works quite the same.
(link to this pattern https://www.raktres.net/seizenn/?sc=Kt3)
I keep working to understand how to better support tablet weaving with Seizenn (notation problems, empty holes)
For this new year I present to you some small improvements for Seizenn.
When you save a pattern, it is by default visible for everyone in the public list. It’s now possible to make it private using the “restrict” button in you private list.
You can have colors in your «loom palette» that are not used in your pattern. Now those colors are bordered with brown like this :
In loom editor you can load default pattern for some popular rigid heddle
You then get
Seizenn was first designed for plain weave or baltik bands. I then added a grid tool. I recently wanted to explore some other weaving technics.
Now you have two new tools.
The first one to draw heddle loom patterns
A second one to draw tablet patterns
Those tools are very simple, I mainly created them to undestand how those kinds of pattern work. They reuse main principles of seizenn, and I just added a few new things like right-click menu in tablet tool.
I could improve them if they would be useful for someone.
In Celebration of plain weave (page 27) Annie MacHale explains how to extract colors from a picture to create a color palette.
Open the Palette tool and go down the page to
You first need to load a picture. You can get a random picture from unsplash.com with or load your own picture with . If you use Seizenn on a smartphone, you can get access to your camera !
For example, with a random picture, you can get :
Then Seizen use two different algorithms to extract colors from this picture :
With the first button, you take all those colors to create a new main palette
But it could be tricky to find yarns with the wanted colors. So instead of getting all the colors in a new color palette, use the second button.
Imagine that you use this main palette (the default one) and that you have all those colors at home
When you click on the “filter” button, Seizenn will try to find de nearest colors in your main palette that will fit the colors from the picture. You then get
(Sometimes, if main palette quite poor, it chooses colors that doesn’t seem to be very relevant)
Clic on “Add colors…” to get those colors in your loom palette and remove colors you don’t want to use.
You are now ready to design a pattern inspired by your picture

Maybe not the perfect tool, but a first try to see if it would be useful for someone.
First of all I would like to thank all those who support me for the creation of this tool. It is with great pleasure that I see that it is being used and that it allows many people to experiment with band patterns. It is very motivating to continue.
I took into account the two main feedbacks I received :
I also tried to extends the instruction page (instruction are not translated into spanish for the moment), mainly to allow users to do the link between the icon buttons and the functions.
An other major improvement is the ability to draw “grid patterns”. The aim and use are a bit different from the traditionnal hexagonal editor.
This tool may not work on old computers. I will therefore make sure to the present version available even when this one would be completely ready.
I hope you will like those improvements and that they will help you for your patterns experiments. Video would be probably needed to show the different functions.
I then decided to update and simplify the seizenn editor. You can found a test version on http://www.raktres.net/seizenn/v2/editor.html, I need some feedbacks before I could replace the present version.
Some improvements :
Fell free to send comments if you find bugs or if something doesn’t work the way you would like to.
Hope you will like it.
University of Arizona hosts a great On-Line Digital Archive of Documents on Weaving and Related Topics.
More than 400 books, 4000 articles… it’s a wonderful collection. Ressources are mainly in english but also in french, german etc.
Hours of discovery and reading.
Some documents, patterns for example, are hosted by https://www.handweaving.net.
