Non-wool lovat blue hose?

[Tobus]

I was wondering if we'd ever get some pics! Yeah, the result you showed is about what I expected, in terms of the colour that was retained. Synthetics just aren't going to take a deep hue when dyed. Repeated sessions may help a little, but I wouldn't count on much additional colour to be picked up. If you do try again, I'd recommend just leaving them in the dye bath for a long time. Days, or even a week.
