For cocoon part, I used the Mystic Mermaid Pattern by B Hooked, for the tail fin I used the Mermaid Tail Photography Prop by Crochet by Jennifer, and for the top, I used the Bikini Baby Pattern by Ashley Designs. I used the Joined Flowers Tutorial pattern by Atty van Norel for the headband.

For the cocoon part I used a 4.5 hook. I followed as written up until the rounds of increases reached the desired circumference. At this point I continued rounds (without increases) until desired length. (Last 3 rows I switched to sc). I used the measurements for desired size from the chart included in the pattern from Crochet by Jennifer.

For the tail fins, I used a K hook and followed the pattern as written up until the part where the cocoon starts. I then crocheted it onto the bottom of the cocoon.

For the bikini top,with an I hook, I followed the pattern loosely adjusting the width and length for the size I needed. I crocheted a ring around the center front and added 5 pearl buttons to the center. I crocheted a chain long enough to attach through the ring and tie in back around neck. In the back I added two buttons to one side so the width would be adjustable.

For the headband I followed the pattern for the flower and added a crochet chain long enough to tie around head. I added 2 pearl buttons in the center of the flower.
