Quite literally (and I mean it, I'm not using it figuratively and saying "literally" when I really mean "figuratively"). My hand is dyed. And the other one too.
I just wasn't in the mood for gloves at our dye day.
Between five of us (some people chose not to dye) we painted two and a half pounds of blue-faced Leicester roving and two and a half pounds of merino roving, as well as a package of silk hankies which we used as dye mops for spills. I think it is as least as good a technique as deliberate colour placement on hankies or mawata. We also dyed a pound or so of bombyx, but that turned out to be easier to fold and dip than to paint.
Wish I had a photo of all the fibre hanging on the line outside Dale's house, as it was gorgeous!
