Knot Magic is how simple as it sounds. Knot Magic is one of the techniques whilst using the air element, "catching the wind" as it was called. Most of what we know about knot magic comes from folk traditions and lore about fisherman and sailors catching winds for their sails and tying fisherman knots. If they need extra wind in their sail, they will untie the knot letting the wind escape these traditions are still prevalent today. Fisherman knots do not unravel and tighter under stress. There are many different ways of how to go about it, you can use rope, twine, thread, string, cord, anything that can be tied in a knot. Color correspondences can be important as well.
In Witchcraft it's very much part one's craft especially if one needs to be bit more secretive and discreet in their practice. Knot magic is much involved in folk magic and what's nice about folk magic is that it's practical and not much ritual needs to go into it. Here are some ways you can integrate it in your practice:
Tying a knot around something that needs to be fixed.
Well, it's easy, you want to capture the spell in the knot and there isn't any wrong way of doing it. Say you want to put reserved energy into the knots so in case you're feeling fatigue or just low on energy and need of a boost. One way is that you take the first section of the twine and chant on what is it you're capturing into the knot I will say talking and chanting is required because it needs to be air flowing and whispering is completely fine as well it doesn't need to be long just say, "I place a piece of energy within this knot." as you begin tying the knot when you're about to tighten it blow as you tighten it. It’s optional but double knots can help secure the knot and energy into place as well say if your saying is a bit too long for a singular knot double knots can be really great for this scenario.
You can also chant while knotting the twine The Witches' Ladder is good for this as well as braiding, here is a simple folk charm to use to create a ladder it's mostly for charms of anything that one would like to achieve and gain. I recommend it for beginners so that you can get the idea and play around and see what you can make out of it
Nine Feathers or anything that can easily be knotted like Hag stones which are rocks with natural formed holes
Make sure the twine/yarn is long enough to hold all nine objects then as you knot the twine chant the following incantation.
'I tie this knot for my need of____.
The next I tie in the Devil's name.
The third to fix it by my will.
The fourth one to hold it fast and firm.
The fifth one to bind it evermore.
The sixth fastens the wish herein.
The seventh brings it nearer still
The eighth makes it almost true
The ninth completes the ladder by which
I climb and reach for____.'
Make sure that you speak slow and clear even when whispering it helps putting, your energy more effectively within the twine or yarn. Imagine as you tighten it that it will never break away like a sailor at sea fasten his sail for the oncoming storm knowing it will never giveaway. You can make just knots with the twine no need of items if you don't wish to I usually don't. You can anoint them in oil or herbal water to bless it. You can write your own incantations and use many other knots.
Use poetry or chanting for me I used the Havamal as Odin speaks that he knows numerous spells I made a belt of said numbered of spells into knots around his glass candle.
I wand dress my wands and staffs, to help preserve and restore energy but also to help grounding and give me a bit more energy in my workings, for this I combining knots and braiding
In regard to braiding, needle work, weaving, though like needle work will have knots at one end and the other it's very few. Whilst doing these activities you can chant, sing, speak, or pushing your energy into each stitch and loom and connector it's mediative and really great for trance work.
Deities Associated with Knot Magic
So this will include UPGS of deity correspondences but within reason and good links that I will describe.
Loki: his name might’ve derive from “knot” and his symbol/sigil is a six looped knot of a snake that is signifies his trickster nature. Now this is my own correlation I don’t know if there is historical evidence of Loki including in Knot magic. However it’s still a good correspondence and working with him. Visualization of knots and finding clever ways to undo them or tie them for mischievous ways. Not to mention he is often associated with spiders who are natural weavers so that can be a great correspondent.
The Norns - Wavers of Fate, they spin the fate of makind. They can help with healing, protection, manifestation, and altering fate.
Frigg- Associated with Weaving as a domesticated art and link to the Norns as she also knows all people’s fates. She is very wise even more so than All father her husband, talk about power couple. She can help protection, Motherhood, healing, wisdom, knowledge, patience.
Athena: Goddess of Craftsmanship especially weaving, one of her famous stories was she cursed a hubris weaver named Archane into a spider who weaves beautiful webs this story is how spiders came to be. Athena is associated with war, wisdom, knowledge, justice, craftsmanship, and strength.
Our Lady of Knots or Mary, the Untier of Knots: This is for people who work in Saint magic or incorporates saints in their practice. Our Lady of Knots is an aspect of Holy Mary. Which she is prayed for resolution of difficult situations in life such as family discord, violence, anger, parents and children conflict like misunderstandings, addictions, lack of peace, martial problems, separation of home or god, and unemployment.

Rán: is a Norse Goddess of the sea who uses a net to capture drowned sailors and live within her hall. Fisherman nets if you ever see one is full of knots again I don’t know there is historical evidence of her within knot magic but she can help with capturing dangers in her net or help soften a blow or change that can be coming without your control.
Britomartis: Goddess of Traps and Nets, often associated with Artemis a huntress and a virgin goddess. Evoke her to help trapping dangers or maybe help you get out of a tricky situation.
Wind gods that can be evoke to let their winds and energy to trap within the knot. Those within the air element.
Odin: He is considered to be the God of Wind, as he was the one to give humans breathe.
Poseidon, Zeus, and Thor as storm gods: Now these gods can cause storms and strong winds especially Poseidon who can create hurricanes. But they can also help with withstand storms (literally and metaphorically).
Hermes: Like Loki he is a trickster god and possibly can help with knot magic as well but he is often associated with the air element.
Hekate: Goddess of Magic but she has elements within air as well, because of being a goddess of magic she can help with any type of intention of use of magic within reason of course.
