Session #6 was using multiple size 10 threads to make a thick weft. In Session #7 (between the two squares below) the weft was changed to 1mm thick natural color hemp from Hemptique.
The hemp aspect is just an experiment; we needed thicker thread and 1mm hemp was simply what was on hand. That was good enough for experimenting. The real solution needs to used cotton or lotus. Hemp would be more difficult to source in remote parts of the world.)
