When I dyed the last lot of fibre I used up some old dye solution, which had been sat in its squirty bottle for a couple of weeks. I was just curious to see if it made any difference.
It worked fine, but it did look as if the dye had crystalised a little in places, as I got a few green granules appearing here and there – they are just about visible in this picture. They aren’t apparent in the finished fibre, but I guess there’s a limit to how long the dye would stay useable?
