Yesterday I rinsed the control and scrunched it up a bit so it was more compact like the colour treated tests. Should make it easier to judge!
The indo test strands are both ever so slightly darker. It’s perfect: You would have to know it’s supposed to be darker, otherwise you probably can’t tell.
I can safely “layer” the indigo until I get the result I want. I figure I will have to repeat this a couple of times to even out the lighter ends. Maybe even set up a schedule, like: Do waist and down first, then classic and down and finally mid thigh and down. Or something like that. I think I will start with waist and down.
