AGM: Turk’s Head Knot

I love Advanced Grid Maker and am the first to admit it’s not pretty or intuitive – it’s one of those tools that needs explaining. If you’ve ever wanted to use AGM but felt lost, here’s an introduction to creating run lists for Turk’s Head knots.

How Big?

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.

Here are some resource that can help you find a starting size for your knot:

And you can learn more about using AGM for size estimates here: AGM: Strand Width & Strand Gap.

For now, let’s say I’m practicing and want to make something like the knot below. It doesn’t matter now, but this happens to be a 7 bight 13 part Turk’s Head knot.

This image highlights the settings needed for Turk’s Head knots. Because they’re common to every knot, I cover certain settings in separate posts.

Column Coding

I wish I understood column vs row coding. What’s important here is that the Turk’s Head uses Column Coding of either UO or OU.

UO vs OU becomes relevant in a later step.

Important: Be sure to click the Column Coding button at least once and every time you change the OU values.

Bights & Parts

While not strictly necessary, it helps to start with a number of bights and parts that’s mathematically possible – the Turk’s Head Size Reference can help with that.

Other AGM features can help you resize a knot as-needed – more on that in a minute.

The Image Pattern

AGM generates both a pattern image like the one above and a set of tying instructions (run list). If you’ve entered a mathematically possible number of bights and parts, your Turk’s Head is ready to go.

If you’ve entered a mathematically impossible number of bights and parts, you may or may not see an image and the run list will have instructions for a different number of strands than you’re using.

While a single-strand Turk’s Head is straightforward, it can be hard to tell if a multi-strand knot is properly formed. For this, check out AGM: Remove Non-Loop Strands

And once you’ve got a feasible knot, check out AGM’s Resize and Stretch features to change the size of a knot or view it in different dimensions.

The Run List

Once you’ve got the correct number of bights and parts, the run list is ready to go. AGM has two formats – toggle the Consolidate Overs and Unders checkbox to view.

Some knots begin with one or more turns around the mandrel. When this is true, the consolidated instructions will indicate it on the first line – the non-consolidated instructions do not show turns.

On a final note, Turk’s Heads are quicker to tie when they start with a series of overs vs unders. If your instructions begin with unders, then switch the coding from OU to UO, or vice-versa and click the Column Coding button.

On first glance, Advanced Grid Maker can seem unapproachable, but with a little know-how it’s a fantastic tool for creating run lists – I hope this helps get you started.
