I keeping thinking scarves should be coloured and that lead to experimenting with dying the silk - using Procion dyes (but I hate these chemicals, and then I would have to try and match with screen printing inks). Then I tried painting the silk with watered down screen printing ink - a blotchy mess.
And then I had a light bulb moment - just today - why not just leave as white. And print using white inks. White on white - very cool.
A bit of a way to go before I am completely happy - in the mean time I'll road test this one. And also try printing on white cotton scarves.
