Useful information before starting

Before starting an amigurumi seahorse project, there are a few things to keep in mind:

  • the seahorse is worked from the bottom to the top of the head, in one piece;
  • start with the body and when you finish the last round, remember to fix the bigger and little fins, sew the mouth on the body;
  • fix the eyes between the 38th and 39th round, with a distance of 11 stitches each other;
  • embroider the cheek with the same yarn of the fins, using the long leaving tail;
  • stuff and finish the rounds, so you don’t have difficulty to get caught in the fiberfill.
