Here's a scarf that I had fun with...
The upper part of the picture is my base layer, where I painted blobs of pastel colors all over the scarf. Next I masked out flower shapes by painting on dye thickener. It's a gooey liquid that stays where you put it and can act as a resist. Painting a dark green around the resisted areas reveals the flowers.
A little freehanding with a black dye-marker gives some loose details. This was a jacquard silk and the weave (the lighter pattern) makes it look almost like water droplets.
A black double border finishes it off. I'm happy to say that this scarf is sold!
