Ok, I'm stumped and I hope someone can help!
I'm dyeing a medium-weight piece of silk with Jacquard acid dyes. The result I'd like to get is kind of an "organic" tie dye that highlights the crinkled fabric, either by maintaining the white "veining" or using a darker color to accentuate the crinkled areas. I've tried to do this by scrunching the fabric together in random spots and tying it with string. The problem is, my dyes are spreading too quickly and I can't keep the crispness of the scrunched areas. I end up with very saturated, almost solid areas where all of the colors have pooled together.
This is the closest example I can find of the effect I'm trying to achieve (scroll down to see the entire piece):
I wash the silk with synthrapol beforehand and usually soak it in half-water, half vinegar overnight. In addition to tie dye, I've tried freezing the silk, LWI, and making free-form scrunches without tying--I just can't figure out how to apply the colors I want and keep them from becoming a giant puddle of muddy brown or black. Another issue is that I'm using squeeze bottles and the dye--especially the black--seems to come whooooshing out, which floods the silk and again, soaks through the white areas. I've read through some of the posts about maintaining crisp lines, but they all seems to refer to other types of dyes rather than acid dyes.
