Dyeing Experiment - Applying Dye with a Spray Bottle

I've been wanting to try different methods of applying dye to yarn.  I saw a beatiful shawl that was dyed after it was knit into a rainbow colorway.  The knitter used a spray bottle to apply the dye, and then sprayed on vinegar to set the color.  The final gradient was stunning.

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?
