AGM: Gaucho Fan & Herringbone Knots
I love interweaves but I can’t do them from sight or memory yet – I absolutely need a reference image and run list. Here’s how to use Advanced Grid Maker to create instructions for the gaucho fan and herringbone knots.
Figuring out how big a knot needs to be and the length of cord needed is somewhat of an art – you need to think about the object being covered, the material being used, and how tight you tie.
You can learn more about using AGM to make size estimates here: AGM: Strand Width & Strand Gap.
For now, let’s say I’m practicing and want to make one of the knots below. It doesn’t matter now, but the left image is a 3-strand herringbone and the right is a 3-strand gaucho fan. Each has 18 bights and 21 parts.
This image highlights the settings needed for the gaucho fan and herringbone interweaves. Because they’re common to every knot, I cover certain settings in separate posts.
It’s worth noting that the color order of strands can make a huge difference with an interweave – especially the herringbone. Be sure to experiment with the order.
Bights, Parts & Coding
While not strictly necessary, it helps to start with a known number of bights and parts.
From the images above, you could say each strand is a 6-bight 7-part Turk’s head and there are 3 strands, for a total of 18 bights and 21 parts.
Related is that AGM uses an OU pattern to design the knot.
The table below shows the bight-part calculations for this example and the OU pattern to use.
- For a herringbone, set the OU pattern and click the Column Coding button.
- For a gaucho fan, set the OU pattern and click the Row Coding button.
- Be sure to click one of these buttons at least once and each time you change the pattern.
The Interactive Image
Once you’ve entered the basic settings and selected either row or column coding, AGM generates an interactive image. There’s several things you can do from here, but perhaps the most useful are:
- Grab and drag the bottom right corner to Resize a knot.
- Use Stretch to change the dimensions – but not the size – of a knot to see how it might cover different objects.
- Use Set Over and Set Under to add detail or stability to the knot – I especially like this for the gaucho fan and herringbone interweaves with 3 or more strands.
The Run List
Advanced Grid Maker generates instructions in 2 formats – toggle the Consolidate Overs and Unders checkbox to view.
Some knots begin with 1 or more turns around the mandrel. This is indicated on the first line of the consolidated instructions – turns are not shown in the non-consolidated instructions. This knot has no starting turns.
Advanced Grid Maker isn’t the most intuitive tool but, with a little know-how, it makes creating interweaves like the gaucho fan and herringbone a breeze – I hope this helps!
