SeiZenn – tablet pattern editor – twits and chunks

There are a few improvements in the tablet editor

Twist counter

First a twist counter that you can activate on “display panel”
At the top, display when there are too many twits, backward or frontward
For twist neutral, or almost, it display number of turns

Reference line

Second, a reference line.
Using right click on line numbers you can add “reference line”
It adds a blue mark for the reference line, and cyans marks for all line that are same as reference

Chunk viewer

Third a chunk viewer.


A pattern can be cut into chunks :

– with right click on border as marks
– using the marks (scissors “cut on marks” )
You can then choose the chunk you want to see. You can add chunk, join the present one with the next one, duplicate the present chunk.
The threading is only visible on the first chunk
The reference is the last row of the first chunk. On the different chunks (apart from first), the reference line is shown at the top.
The end of the chunk “should” be the same as the reference line so that the different chunk could be woven in anyorder. If it is OK, the square is black, otherwise it is red

The twist counter only take into account the present chunk.
As an example, I reproduced a pattern from the great book  “tablets at work” by Claudia Wollny, p406
You can choose the chunk you want to see

Tissage aux cartes


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.


A few improvements for this new year


For this new year I present to you some small improvements for Seizenn.

Lists of patterns

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.

Loom colors

You can have colors in your «loom palette» that are not used in your pattern. Now those colors are bordered with brown like this :

Rigid heddle pattern

In loom editor you can load default pattern for some popular rigid heddle

You then get

New tools

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.
