Yep, I do the tail, then the hair. Once it's completely trimmed I glue in the fins, mohawk, etc. with gel super glue. On those I did one clump on bottom three on top. So on the second one it went one big chartreuse bundle on bottom, a blue bundle about half that on top, then a thin bundle of orange and a bundle of black about the same as the blue, then I repeated four times down the hook. That fourth set was a real pain to get on the hook. The trick is to have your top bundles add up the the same thickness as the bottom bundle to make your center line actually in the center. Believe it or not I just pack the hair with my fingers.
