This is a pattern for a ladies cardigan : the mermaid vest.

A very comfortable and sweet shrug-like vest. The back and shoulders are in a very comfortable stretchy pattern, and the large collar has a lace pattern.

I have made full written instructions for size medium, the vest is very easy adjustable to other sizes, and I explain how to do so.

You can also choose another size crochet hook : if you want to use thinner or bigger yarn.
