I have just finished a mohair scarf. I followed the general warp making instructions on a warping mill. I got a perfect warp on the loom. I think lack of ties was helpful with mohair, also I didn’t leave the warp long before putting on the loom so the fibres didn’t get a chance to settle and grip on each other. Best tip was direct tie up and raising each heddlr separately. I have woven mohair before and it was a slow and frustrating process. After following Janes instructions I am so happy with results.
