Any of the Jacquard or Dharma acid dyes that contain blue end up giving me fits – even if I reheat and think I’ve totally dissolved the dye, I end up with tiny clumps. I tried filtering, but of course, end up loosing most of the dye itself. Anyone know of any solutions to the blue dye solution problem???
Next day: Of course, I should have gone straight to Ravelry; the Love to Dye group forum. Apparently this is not an uncommon problem with blues – or reds or yellows. One suggestion is to add a tsp of rubbing alcohol or Urea water to about 500ml of dye stock. Definitely will try this.
