How to use Not So Rigid Designer

Overview #

The Pick up Designer tool lets you create designs using pick up sticks, colors, and different threading options in one or more heddles. The format is inspired by weaving drafts used by shaft loom weavers, but adapted for rigid heddle.

This video shows an overview of how to read the patterns.

There are 3 main areas of a pick up design:

  1. Threading (Top)
    The rows labelled H1-H3 are the heddles; a circle represents a hole and a square represents a slot. The rows labelled with a single letter (A, and B in the example) represent pick up sticks. A black square on a pick up stick represents a thread that has been picked up by that stick. The warp colors are shown in the top bar.
  2. Weaving Sequence (Right)
    Each column represents a different heddle and stick. Clicking on the heddles and sticks will toggle between valid positions for that heddle or stick. This is like the treadling or lift plan section of a shaft loom draft. There's also a column near the right for weft colors.
  3. Drawdown (Middle)
    This shows the interaction of the warp and weft threads - a preview of the final fabric. Note that like the drawdown in a weaving draft, this doesn't account for all of the 3d interactions of threads and sometimes the fabric can look quite different after wet finishing.
Example of a design

The example above shows a design using 2 heddles and 2 pick up sticks. H1 represents the front heddle, and the heddles are in the 'standard' 2 heddle arrangement. Stick A is 1 down, 1 up, 3 down, 1 up, 3 down, 1 up, while stick B is 1 down, 1 up. The warp and the weft are mostly white, with a teal color in the rows and columns where there are floats. Stick A is used with the heddle in Up to produce warp floats, while stick B is used with the heddle in neutral to produce weft floats. The heddles are mostly used up and down together, except in the middle area where a pattern is produced by mixing up and neutral positions.

You can create designs using up to 3 heddles and up to 10 pick up sticks. Heddle 1 is the 'Front' heddle on the loom.

Toolbar #

At the top of the design is the design's title and some buttons to Undo, Redo, Save, Edit a Copy, Download Image, set the size to small, medium, large, or extra large, display some information about the draft, and, on the far right, show the keyboard shortcuts.

The toolbar buttons

You can edit the title and save to update the title. The Save button will also save any changes in the design.

Undo/Redo let you undo and redo changes to your design.

Edit a Copy will save the current design as a new design with a title starting with 'Copy of'. This is great when you've started tweaking your design but still want to keep an older version.

Download Image will save an image of the current design to your device. You can print this out, share it on social media, add it to project notes on Ravelry, etc.

Clicking one of s, m, l, xl will set the size of the design, that is make all of the squares etc. bigger or smaller. The current size is highlighted in grey.

The Info button will display some information about the design - currently the number of threads in the warp and weft overall, and by each color.

The Shortcuts button shows the keyboard shortcuts. They're noted here in a different font and color, like c to toggle the color modes.

Many of the more complex functions described below are found in the Sidebar. This is on the left hand side of the screen on larger screens, and below the design on smaller screens like a phone. Each section has a header which in most cases includes a summary of what's currently enabled; click on this header to expand or collapse the section.

The sidebar menu

This shows the sidebar with the Color section expanded, showing the starter color palette.

Create a Design #

If you're using the demo version, the basic design is already created. Refresh the page to clear it and start fresh.

To create a design, click on Pick Up Designer on the left, then click the Create Design button. Give your design a title, and optionally set the number of warp and weft threads, the a number of pick up patterns and heddles, and your starting color palette. You can edit all of these after starting.

Select your starting color palette #

You can choose to start with just 2 colors, black and white, or, a starter palette of 26 colors that cover a range of basic colors in a few shades. In both cases you can add, remove, and change colors after you start a design.

Choose Black and White if:

  • You already have some yarn in mind and want to precisely match it
  • You want to work with many similar colors, for example, a gradient with 5 different shades of blue
  • You'd like to just focus on texture

Choose the Starter Palette if:

  • You want a starting point for colors rather than a blank slate
  • You prefer not to fiddle with a color picker to get a close match
  • You want to be able to quickly make major color changes ("Red" to "Dark Purple" to "Blue") and then refine later

Edit your Design #

The Edit modes are where you change the threading and heddle positions. Shortcut e returns you to the default of Edit for warp and Edit Single Heddle for weft, while f also goes to Edit for warp but Edit All Heddles for weft.

Set the Threading (Warp) - Pick up sticks and heddles #

When in Edit mode for the warp, you can add or remove threads from pick up sticks, and change threads from hole to slots and vice versa. The heddles are represented by circles (for holes) and squares (for slots), while the pick up sticks are the rows of squares above the columns where all heddles are slot threads. Each column represents a thread on the loom.

Clicking on a heddle will change it from a hole to a slot or vice versa. Changing from a slot to a hole will remove all pick up sticks set for that thread. In multi heddle set ups, each thread can only go through one hole, so if it's already in a hole in another heddle, the hole will move.

Clicking on a pick up stick will change it from on the stick (black) to not on the stick (white) the pick up stick. If starting from a design phrased as "1 up, 2 down", you would want one black square, then 2 white squares.

Note the video is out of date, there is now one Edit mode for editing the sticks and heddles.

 

Set the Weaving Sequence (Weft) #

The weaving sequence area on the right sets the position of heddles and pick up sticks for that row of the weft. A heddle can be Up (▲), Down (▼), or Neutral (–); Neutral heddles replace down heddles when there are other heddles that are up or a pick up stick is in place. The following combinations are valid:

  • A mix of Up (▲) and Neutral (–) heddles, and sticks
  • A mix of Down (▼) and Neutral (–) heddles, with no sticks
  • All heddles Neutral (–), with at least one stick in use.

Each column represents a heddle (H1, H2, H3) or a stick (A, B, C, etc).

In Edit Single Heddle mode, when clicking on a heddle:

  • If the heddle is Up, it will go to Neutral if there are any other Up heddles or sticks in that row, otherwise it will go to Down.
  • If the heddle is Neutral, it will go to Up if there are any up heddles or sticks, and Down otherwise.
  • If the heddle is Down, it will go to Up if there are no sticks and any other heddles are Neutral, otherwise it will go to Neutral.

This means that you may need to click in a few places to make major changes to a shed in this mode.

In Edit All Heddles mode, when clicking on a heddle:

  • If the heddle is Up, all heddles in that row will switch to Down, and any pick up sticks will be removed.
  • If the heddle is Down or Neutral, all heddles in that row will switch to Up.

In other words, it "forces" other heddles to change with it.

In both of these modes, clicking on a cell for a stick will add or remove the stick. If the heddles are all neutral, and you remove the last stick, the heddles will go to down. If any heddles are down, and you add a stick, the down heddles will go to neutral. If you selected "Allow using multiple pick up patterns together" when creating your design, you can have multiple sticks, otherwise, clicking on another stick position will remove the existing stick from that row.

Adding and removing warp and weft #

Select the appropriate Warp or Weft mode from the sidebar on the left (larger screens), or below on smaller screens, or using one of the keyboard shortcuts you can find in the shortcuts menu. Some, but not all, shortcuts affect both warp and weft.

To add a warp thread, choose the type of thread you want to add from the Warp Mode section - hole, slot, or, both a hole and a slot (shortcuts h, s, and b). Then click on the heddle row where you want to add the thread; the selected thread will be highlighted in green. Similarly, to remove a warp thread, select Remove as the Warp mode, and the selected thread will be highlighted in red. To stop adding or removing threads, select Edit as the warp mode. Warp threads (holes or slots) are inserted to the right of the selected thread, and in multiple heddle setups, the hole will go in the heddle you clicked on. Basic users can add threads up to a limit of 225, while Premium users can add up to 300.

To add or remove a weft thread, select add or remove from the Weft mode, and then click anywhere in the weaving sequence area. The square will highlight in green (when adding) or red (when removing) instead of the default teal. Weft threads are inserted above the selected row. The shortcut key for adding a weft is a and for removing one is r.

To stop adding or removing threads, go back to one of the edit modes, either via the warp and weft options in the sidebar, or shortcuts e and f which both set the warp mode to Edit, and the weft mode to Edit Single Heddle and Edit All Heddles respectively.

On the loom, 2 holes or 2 slots next to each other can represent either 2 yarns through the same hole or slot, or, an empty slot between 2 holes or vice versa, depending on the desired sett of the fabric.

 

Changing Colors #

The currently selected color is shown in the header of the Color area of the sidebar. The warp and weft colors are controlled using the top row (warp) and rightmost column (weft), and show throughout the drawdown area. You can choose between Edit Selected and Replace All color modes here, or toggle between them by pressing c.

Change a single color or adjacent colors (Edit Selected) #

To change the color, choose a color from the color palette in the Color Selection menu in 'Edit Selected' mode, then click on the warp or weft color at the top or the right of the design.

You can also click and drag to change several adjacent thread colors at once. This currently works best with a mouse; on a touch device it works best if you zoom in.

Replace All threads of a color (Replace All) #

You can replace all of a color in the warp or weft. This is useful when you have several stripes of a color, or a large area of the color that is cumbersome to drag. Set the mode to Replace All, select a color, and then click on a color in the design. If you click on a warp color, all threads of that color in the warp will change, likewise for the weft; if you want to change the color in warp and weft, click on one and then the other, or, change the color in the palette.

 

Change the color palette #

The buttons below the colors let you change the color palette. You can add a new color, change an existing color, and delete a color.

The Color Palette Buttons

To add a color, click on the '+' button, and use the color picker to choose a color. You can change the hue by dragging along the bottom, and pick different shades in the area on top. The color picker starts with the currently selected color so you can easily make a similar color. The button will be disabled if you've hit the limit of colors based on your subscription type (3 for the demo, 26 for basic, and 50 for premium).

To change a color, select it, then click the pencil button, which will open up the color picker as above. This will change the color in the palette, and everywhere it's used in the design.

To delete a color, select it and then click the trash can button. You can't delete a color that's in use in the design (change it to something else first!).

Change the grid lines #

The grid lines show in the drawdown and help distinguish different threads. You can choose to turn them off, to focus on color, or one of 3 different shades of grey for more or less contrast with your design, using the radio buttons below the color palette. The animation below shows the different options - the default color is a medium grey, light is not quite white and dark is not quite black.

Animation showing the different grid line options

If the grid lines are off, you won't see textures in areas where warp and weft are the same, but it can help you focus on color. Your selection here will show when you download an image, but isn't currently saved when you reload.

Change the number of sticks and heddles #

The Heddles and Sticks section of the sidebar lets you change the number of heddles and sticks after starting a design. It lets you add, delete, and also toggle allowing multiple pick up patterns in the same row.

To add a heddle or stick, click on the appropriate add button. There is a limit of 3 heddles and 10 pick up sticks, and the buttons will be disabled if you hit it.

The Heddles and Sticks section with delete disabled

To delete a heddle or stick, ensure the "Delete Heddle or Stick" switch is on (pictured below), and then click on a heddle or stick label. When delete is enabled, the heddle and stick labels will highlight in red when hovered. Turn the switch off when done to prevent accidentally deleting while editing your design.

The Heddles and Sticks section with delete enabled and the advanced menu open

You can also enable or disable using multiple pick up patterns in the same row using the Advanced section. This would usually only make sense if your patterns are mounted on heddle rods and you are lifting more than one to weave the same pick.

Premium Features #

The following features are available for premium subscribers. Those marked with Preview are planned to come to Basic users soon!

WIF Export #

WIF files, or Weaving Information Format, can be used in many other weaving programs. You can export to WIF from the list of designs (e.g. select Pick Up Designer from the home page), using the Export button. I am continuing to work on improving the mapping to shafts over time.

Repeat Design (Preview) #

The repeat design section of the sidebar lets you repeat the entire warp and/or weft multiple times, to quickly build up a larger pattern from a smaller one.

Select the number of repeats you want for each of warp and weft, then hit apply. Leave the value at 1 to leave that part unchanged.

As an example, if you have a design with 10 warp threads and 8 weft threads, setting warp and weft to 2 and hitting apply will result in repeating each of warp and weft to have 20 warp threads (10x2) and 16 weft threads (8x2). If you use the tool a 2nd time, and set warp to 3 and weft to 1, you will end up with 60 warp (20x3) and 16 weft (16x1) threads.

As a Premium user, your design can grow to up to 300 threads in each of warp and weft; the apply button will be disabled if you would exceed that.
