Tying notes: Some say you can’t stack calf tail. Maybe it should be better stated as calf tail doesn’t stack easily. I stack the calf tail in this pattern. Use a bone comb to semi align the hair. Place the tips in first using a large stacker. Rap the base of the stacker a few times. Separate the stacker and pull the tips out. Comb the hair again and repeat the stacking process. They should be aligned fairly well at this point. Just remove any hairs that are out of line. In my opinion this pattern works well with jungle cock nails that are on the larger size.
