So once the horse hair has been threaded onto the kumihimo loom, the start and finish are the really challenging bits.
In each warp in the picture here are 9 horse hairs. 9x8=72. That is, 72 horse hairs to keep control over as the braid starts to be woven and 72 hairs to maintain the tension in as the braid develops. Once the braid gets going though, the process is much easier.
To make things really easy, I have a vase so I can place the disc down whenever I need to. That way, nothing slips or gets dislodged.
To help keep tension in the braid you can use a plastic bobbin to hold the end of the hair plus attach a weight to this also. I use a key.
Always start on either side of the dots.
Start moving the strands of hair from lower left to upper left followed by upper right to lower right.
Once the upper and lower warps have been moved the disc is turned ( turn clockwise, but it doesn't matter, so long as you always work in the same way)
You then move the next four warps in exactly the same way.
Once done, all of the warps will have moved one place to the left (or right depending on how you are moving, clockwise or counter clockwise)
Now you continue until you reach the length you are looking for in the braid.
Here the bottom left warp has moved to the top left. Now you can go and have a coffee and do other things. When you return, you will know that the next move is upper right to lower right.
