If you are really into dying things and have connections via family or friends or your spouse, have your feathers dyed by a hair dresser. With today's crazy colors, they can dye your feathers or whatever, any color and shade you want. My daughter is a professional hair dresser and she dyed a dry fly neck hackle the best silver blue dun I have seen. She took about 6 feathers and dyed each one slightly different to find the color I liked. She then dyed the neck the color and shade I selected. It only took about 30 - 45 minutes. It was great!!
