I found the Ladder Rings where they added a link to the (free) instruction. But you have to register there and I don’t like this.
So I figured out how I would do it and that’s what I came up with (it may be that their instruction is completely different):
That’s what you do:
You need two sizes of beads which are to be linked as seen in the diagram.
If you’re ready it doesn’t look very good because there are really gaps between the little beads as in the diagram.
That’s why you pull the thread once more through all little beads – the ring is finished.
Caution: The second step tightens the ring considerably.
I made my first ring much too narrow because I didn’t know that it gets smaller in the second step.
Unfortunately I can’t say how much.
At the second try I did it differently: I repeated the first step until I thought that it should be enough, then I pulled the thread through the little beads on one side and tried if the ring fits.
It didn’t, so I pulled out the thread from the little beads, repeated the first step two more times and then it was right.
