I've got a small break from my endless projects for the order of a Mermaid set.
This time I had a different and a bit more complicated approach to make the tail.
I chose a pattern with the shell stitches, so that it looks like a fish scales. And I started my work from the top with the ridged rib pattern, then cast on stitches for the main pattern. For that I took some idea from here.
And here is the pattern.
