Hi
I was asked for simple instructions for beginners. I began with two short introduction sheets.
The first one is a presentation of the interface :
The second one is a basic reminder to create a very first pattern with SeiZenn.
I took some elements from Instructions for using V1 Seizenn by Annie MacHale
Hi
For Christmas, I received “The weaver’s Inkle Pattern Directory” by Anne Dixon. In this great book, she presents lot of different technics.
Many patterns from this book can be reproduced with SeiZenn. One of the last add is krokbragd button :
Some technics would be very difficult to add to SeiZenn, and for, I think, a limited benefit. For example fringes (page 154) or pleating (page 130).
I thought it could be interesting to add an inlay mode to create brocade (page 138).
With this mode selected, you just click on the pattern to draw brocade pattern 
It comes with a few tools : 
=> 
A pattern can be cut into chunks :
Hi
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
We obtain
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)

Hi
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.
Simple idea may take time to emerge.
Up to now, in Seizenn, there were two ways to draw a baltic pattern.
1) In the mode “ Edit an inkle loom pattern”, you can play with pickups and drops thread by thread. I will refer to this as the “realistic tool”.
2) In the mode “Edit a square pattern” you can create a grid (or block) chart. I will refer to this as the “Baltic grid” mode.
Grid charts are more common for Baltic pickup patterns, but they do not give a realistic preview of what the resulting band will look like.
As both are useful, I was asked several times to be able to switch from one to the other and back. I was quite reluctant because it would have been very difficult to program and it would have work in very few cases. The two tools work a very different way, you can draw pattern in one tool that would be impossible to create with the other (three color pattern, carpet pattern etc).
With the experience of what I did with tablet weaving tool (sulewasi mode), I tried an other way to fulfill the need, far simpler.
In the realistic tool, in the “Edit Mode” panel I just added a feature that allows you to select “baltic grid”. It will not work for 3-color pickup patterns, it’s just for simple 2-color baltic patterns.
For a 5 min video => https://www.youtube.com/watch?v=wQToadxlWv8
When you select it, you switch from
to 
To use this mode, you need to adjust where the baltic grid begins on the left and where it ends on the right.
In the threading pattern, you see the first blue dot is done with the 11th thread, and the last one is done with 29th thread
When you select “baltic grid”, new options become available in the “display options” panel.
In this panel, where it says “Threads” set the “first” and “last” values, 11 and 29 in this example.
You can then click on the grid to create your pattern
If you leave the “baltic mode”, you can see the result
In the “Display Option” panel you can also adjust opacity of the grid with the “baltic visibility” slider.
If you create a picture while you are in “baltic grid”, the grid pattern will be visible. Thus you can choose the pattern representation you want during weaving.
When you use 
or Sunna Heddle pattern
, first and last parameters are set automatically.
In the “Edit Mode” panel, when you select “baltic grid” mode, a “selection tools” checkbox appears. If you check this function, new buttons appear.
You can then select an area on the grid with you mouse. The area is surrounded with dashed blue and yellow line.
When an area is selected, you can act on it using the different buttons. For example you can flip it horizontally.
You can also copy and paste an area. With this selection, click on “selection copy”
Animation showing copy and paste
you may notice that a representation of the selected area appears on the tool panel.
You can then select the up-left point of the place you where you want to paste the pattern.
Then click on “selection paste”, you then get :
Animation showing how to copy a pattern from square tool.
There are limitations. For example it may not work if you have two baltic patterns side by side on the same band with a plain weave gap between the two. When you save a pattern, grid position is not saved. Of course will not work for 3-color patterns.
Hope this new mode will help you.
From Flaab I also bought a small rigid heddle. Back home, I wanted to try it on my weighted frame and chose to experiment 3 color patterns from Annie MacHale (https://www.taprootvideo.com/preview_class.jsf?iid=12&cid=2)
As the heddle is quite narrow, 31 threads, some modifications were needed. The first idea was
I then decided to modify it to get a 3 color pattern on both sides (and changed border threads)
Modifications are very simple and not obvious with a white weft. To show them, here is the pattern with a red weft.
Everytime I pick up a thread, I drop the right next one. Very easy to do (that was my first 3color band) and result is nice.
Here is a picture of the setup 
The two faces of the band.
Bonjour
Petite pause estivale.
J’ai commandé auprès de Flaab des cartes de tissage en bois que je recommande vivement.
Pour les utiliser partout, j’ai construit un petit chevalet qui peux être utilisé seul
ou avec une ceinture.
Les poids sont faits avec des boulons de roue de voiture (80g) enveloppés dans des petits sacs en tissus.
J’ai choisi un motif simple assorti avec le lieu.
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”.
It matches the colors of the set sold here https://shop.stoorstalka.com/en/products/handicrafting-diy/yarn/ahkko-yarn/4-pcs-ahkko-sami-colors-bright-red.html.
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 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 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.
Hi
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
https://www.raktres.net/seizenn/#/heddle
A second one to draw tablet patterns
https://www.raktres.net/seizenn/#/tablet
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.
Jeff
