I've also finally cracked the best way of turning the teasels black. Spray paint too much mess, waste and smell. Black dye doesn't seem to get absorbed through outer layer. But Nina suggested Indian ink, so I tried some Quink first and then a small bottle of Indian ink and have now placed a large order! I hope to be able to dip the teasels in bunches and speed up the whole process. Indian ink is apparently made from soot.....

Can you tell the difference?
