I've also been finishing my machine thread colour scales for my other class, and I overdyed these fabrics - adding bright green and magenta. They're more interesting now, but I may do another round of colour. I am curious about how different methods of dyeing compare to each other. I used low immersion methods here - with three hours of batching and a different recipe and the results are as vibrant as the tray dyeing. It seems to me there's room for alot of leeway.
