The crochet octopus (Bläckfisk) is originated in Sweden where groups of crocheters make them and give to NICU’s around the country. The octopus gives the premature baby security and the long twisty arms remind of the umbilical cord and the time in the womb.

My notes: I held the yarn double. Also did some modifications to get the size I wanted (more increases and a different decrease).
