Lay your serviette square out flat before you in a diamond shape.
Take the point at South and roll it up as tightly as you can until you reach the North point. You should have before you a long narrow tube of material.
Bend the ends (the East and West points)together as if you were making a knot, but instead of doing so, make a loop around the circle and then pass the East point into the centre of the circle to secure it. The West point can either be taken into the circle from the other side to secure or it can be carefully tucked into one of the diagonal folds of the centre circle.
In the very centre of the circle the North point will either tuck under neatly or it will point up a little (this depends entirely on the size and firmness of your serviettes).
