I used a merino blend for this sweater. The main colour is a teal green and the fish are worked in a mauve or antique rose colour.
I made a few changes, knitting the arm ends without ribbing. Same with the hem of the sweater. I instead used a leftover yarn in baby pink to knit a few rounds of stockinette and 1 round of garter stitch before casting off. I made a double ribbing on the neckline and also crochet a picot border on the bottom of the neckline ribbing.
