That's dyeing, not dying. Silk scarves, in fact. A few of these have even made it into my Etsy shop. The ones I dyed today will make their way into the shop in the next few days.
Normally, I dye during the day so I can see the colors in natural light. However, and this is a big however, I couldn't sleep last night so at midnight I got out my dyes and an piece of silk that I had sun dyed in cochinel a few years ago and ranged from deep red to pink. It was kind of pretty but not precious. In other words, an ideal candidate to experiment with. I hauled out a handful of itty-bitty hair bands and randomly bound the scarf. I wish I'd taken a picture because a bound piece of fabric is kind of cool looking. I threw it into a basin to soak. While it was soaking, I choose a lovely brown dye with a bit of a gold tone. After mixing up the dye, I threw everything into the dye pot, everything that is but enough acid.
After all the dye exhausted, I pulled it out of the pot and rinsed it. The dye was bleeding a bit, actually quite a lot. But it was very late (or early depending on your point of view) and I released the bindings. It was lovely, really lovely. Except my hands, which were not; they were a weird gold-y brown. It was then that the light bulb went off. I needed to throw the silk back in the dye pot with enough acid to set the dye. This changed the color of the areas that had been bound. I was disappointed! But it was very late and I was finally sleepy.
