My shop helper, Cheeto, is trying to figure out how to tie knots. This is my process for starting a new rug. I leave the previous warp threads on the loom, wind a new warp onto the beam, then tie it onto the previous one before pulling it through the heddles and reed. It takes anywhere from 3 - 6 hours to get the new warp on the loom. Maybe longer with Cheeto's help!
