Today I focused on leaving the fabrics in the indigo for a longer time period, and most did come out darker. This silk velvet spent one hour in the bath.

And this is cotton - also one hour.

And some trim and silk organza - which remained a turquoise in spite of being longer in the bath.

And overdyeing with indigo - on a piece I had previously dyed green, just to see what would happen.

I am learning something with each dip and I can also try successive dips with one fabric, to see how that works to darken the colour.
