If you have done
some scoubidou you know the crown knot with four strands, the first picture
below. You can also tie this knot with two strands at a time. If you do not
know the knot, go to the website for more explanation. You can also tie this
knot with more strands, one at the time, below there are pictures for six and
eight strands.
If you tie six or
more strands into a string it becomes a hollow tube. If you want the tube to
be sturdy, tie the knots over more strands. Below the drawings for tying over
three, but over two or more than three is also possible.
When you make
bigger object you will find often the strands are not long enough. A good looking
way to replace your strand is as follows. When one of your strands becomes
short, place a strand in the center of the knot, (where the hollow of a tube
would be,) tie a few more knots and then exchange place with the short end.
Tie a few more knots and cut the left over bit short. With a bit of practice
it is nearly invisible.
