A little blurry with the cropping, but you get a sense of the segmentation and fibers/barbs of the peacock herl, which in this instance was dyed. This is an excellent material for smaller abdomens, thorax and heads.

I heared they have smaller peacock eyes for smaller flies like # 20 I have not seen them but it would be nice for some smaller patterns .
