I use this knot to attach my kite to my flyinglines. I'm sure this knot has another name also, but my friend MÃ¥rten gave it the name "Stockholm knot" because he was in Sweden when he discovered it.
On the end of my flyinglines I have a loop like this with a smaller loop att the end. I leave you with the choice of which knots to use to make your loop.
On the bigger loop I then make a lark's head.
I make a knot on the end of by bridle line and thread it through the lark's head.
Then I pull both ends of the bridle line and on the flyingline to tighten the knot.
To open the knot I pull both ends of the bridle line and the small loop on the lark's head.
