I presoaked the mini-skein of yarn in a vinegar/water solution before spraying on some dye. This would have worked better if I had more liquid in the spray bottle, but I didn't want to waste any food coloring. I then wrapped the skein in seran and set the color in the microwave.
The final effect is handpainted/kettle dyed-esqe. I was wondering if I would get a frosted color like in some Madelinetosh yarns, but I was dealing with a fingering weight yarn. Using a spray bottle on bulky yarn may apply the color just to the outside giving the frosted effect I covet.
I also think that this method would be easier with more liquid in the bottle. As I mentioned at the end of the video, I have a spray bottle that is a LOT better. I've learned a lot from this experiment. So tell me, would you even give dyeing yarn with a spray bottle a try?
