Inspired by the many tails out there. I just started with a magic circle and 6 Dc then increased to 18 then to 24 dc. Then started crocodile stitches in the round increasing each row. When I got about 12 rows up I started working back and forth so that there is an opening from that point until the top increasing at the start and end of each row. I did this until it was the size I wanted (really I just kept going until i didn’t have enough yarn to do another full row) The fin I started with a chain of 30 and did a row of DC then each row was dc. The top of the fin I kept straight, the bottom I decreased 2 and then another decrease after turnign the next row. I did this until I had 15 DC in a row then started increasing following the same pattern as the decreases (2 increase DCs as I worked to the end of the fin and 1 increase at the start of the next row working away from the fin). Then I gathered the top of the fin a bit and sewed it onto the bottom of the tail just below the first row of crocodile stitches.

Was easy to free hand so I didn’t rely on a specific pattern despite there being several that are similar if not the same.
