Instead I was experimenting with plant dying a bit (also to pamper my little soul after the failure on that neckline).
So I used untreated wool yarn and this was the result -

The Japanese indigo leaves require no mordant and can be applied cold which makes it great. I loved using it - too bad I only had enough for one skein of merino yarn.
The rest was with 14% cold alum mordant
