Hi ALL,

This is my first post and I'm a new member of [IGKT](https://discourse.igkt.net/t/igkt-international-guild-of-knot-tyers/9985). Please help me to find a source or reference for this knot in question. I've been looking for over a year now. It's not in [ABOK](https://discourse.igkt.net/t/9845). I haven't gotten an answer on Facebook. IGKTNA hasn't returned an answer. So far some have said they've seen this knot without reference, and some have sent pictures of somewhat similar different knots.

I discovered this knot looking for a triangular mat to cover the breasthook of my boat. It was derived from a 4x3 Turks Head, and is actually three symmetrically interlaced figure eight knots. I like to call it a Triangular Thump Mat.

Thanks for looking and I will be appreciating any comments!

I am afraid I can't help on whether this is a new knot or not, although I can say I've never seen it.

What I will say is it it absolutely **beautiful** , both in its internal elegance and its outward appearance, and a welcome addition (hopefully) to the range of mat knots.

Is there any special trick to tying it, or just start from a single figure-8 and go from there?

Thanks for your kind words. As far as tying, you can start with two figure eights in a line, and then weave at the center to start the third figure eight.

You may want to get in touch with You-Tuber named "MARSALA" who on 19 October 2019 made a video that looks similar to yours. He was inspired by a colleague from [IGKT](https://discourse.igkt.net/t/igkt-international-guild-of-knot-tyers/9985) France.

@Christopher_Corfman would you perhaps change the title of this topic to your preferred name for this knot?

Shellback7,

With some ChatGPT help I was able to dig up this video from the channel Noeuds Marins Par Marsala:

![](https://discourse.igkt.net/uploads/default/optimized/2X/b/bcdc257ddbe8324fc62342c10d9fdb83ae9a744e_2_690x388.jpeg)https://www.youtube.com/embed/adUqS1ids44?feature=oembed&wmode=opaque

That is a knot derived from a 2x3 Turks Head, a different knot.

@Christopher_Corfman thank you for sharing this design. I've made a copy in 16mm sisal and can confirm it's two same-handed figure-8 knots in series, then overlap the outer loops, and weave the final figure-8.

A lovely knot, would work perfectly around a jibstay/headstay deck plate.

I'm away on honeymoon at the moment (married my equally crafty wife on International Knot Tying Day a couple of weeks back!) so I don't have a sail needle and a sailmaker's palm with me, so the final finishing will have to wait till I get home.

If you read my e-mail I said it is similar and not the same knot.

shellback7, agree, and there’s a relationship: 2x3, 4x3, and then I believe the next iteration 8x3. Also I think it’s interesting where the 5 sided compartments lie in the two knots (and in the 8x3?).

If this knot exists, ask Marsala, he is very competent

Bonjour à tous

Comme beaucoup, j’ai l’impression de l’avoir vu passer sur la toile.

Mais je n’ai pas souvenir l’avoir vu dans un livre de noeud ou matelotage.

Peut être l’as tu réinventé 😀

Je serai très content d’en faire un tuto vidéo, mais je t’avoue que les premières étapes m’aideraient pour le démarrage du nouage.

En tout félicitations car il est très original.

Il est vrai que le [abok](https://discourse.igkt.net/t/9845) reprend beaucoup de noeud mais seulement ceux que l’auteur a croisés, ce qui est déjà énorme.

à bientôt

Anthony

Bonjour Anthony,

Je l'ai réalisé à partir d'un nœud de tête de Turc 4x3. J'ai vu votre démonstration concernant un autre nœud triangulaire similaire, dérivé d'un nœud de tête de Turc 2x3. En théorie, je pense qu'il serait possible de créer un nœud similaire à partir d'un nœud de tête de Turc 8x3. Je serais ravi de vous envoyer une série de photos illustrant les différentes étapes.
