A mixture of soumak (i-open, ii – alternate closed and open with staggered rows), half-hitches over the next warp (giving the knot to the front), vertical wraps on two warps (essentially a sort of climbing open soumak), and loops. These are standard loops – i.e. they are supported only by subsequent packing, and can be pulled out from the rear. I’ve since realised one can lock them in by looping back under the previous warp.
The plan is to have hems top and bottom, so no braids will show. Once off loom and all sewn down, the ideas is to cut the looped areas and have patches of tufted pile.
