For those of you who do crochet out there, here’s a pattern for a blanket with a Koi fish on it! Note it is a paid pattern, here's the link:
Worked in an easy crochet diamond mesh with shell stitches for the motifs, the fabric has a soft drape and is breathable and comfortable. Construction begins with the central panel. Then the surrounding rows are continued around all four sides, with the option of adding extra width at left and right. Two layouts are provided for the motif charts – one for fingering weight yarn and one for DK weight yarn.
