top fin, knit (k1p1 rib) each orange section separately with shortrow shaping to get a curve at the top, leaving the stitches live. Then I picked stitches up along the hat for each black section, joining each row to the orange as I went, and curved it around the top of the orange with a few K2tog and knit across the top for a couple rows. Then I joined white and the start of the first orange section, knit across the first fin, down the side, across the top of the hat to the other fin, and made a few short rows to fill in between the fins, then picked up and knit up the side of the second fin and across the top. Did a row or two then did a stretch b/o

I think I should have made the tail a little longer. Knit the tail (k1p1 rib) in the round with short row shaping to round it out a bit, then did a three needle b/o.

Added some short row shaping to the side fins as well. Picked up less stitches for the ‘lucky’ fin and made it shorter. I rounded up the corners of the fins a bit by pulling the ends of the yarn a bit tighter when I weaved them in.

Made a second hat. Changed the top fin a bit and the tail. I like the fin on the first hat better as this one is too tall. The tail on this one is better, matches the fins better. -combined stitches and knit flat instead of two layers in the round.
