If an amigurumi piece has embroidered details, it’s usually the very last step. These tutorials walk you through a few common details you might want to embroider onto your amigurumi to either give them a little bit more pizzaz or, in the case of embroidered eyes, make them safe for kids and pets.
The main concept behind embroidering anything onto amigurumi is that you want to start and end your embroidery at the same place, tie a knot in those yarn tails, and weave them in. As an example, here's a photo tutorial on how to embroider a nose with a mouth.
1. Thread a tapestry needle with the yarn or thread you’ll be embroidering with. Insert it into the piece, and out again through another point in the piece.
2. Pull the yarn through and leave enough of a tail – about 6 inches will do – so that you’ll be able to comfortably thread the yarn tail later.
3. When you’re done with your embroidery, take the needle out of your piece through the same point as the yarn tail.
4. Take the needle off, and trim the yarn to the same length as the first yarn tail.
5. Tie a knot with the two ends.
6. Thread the needle with both yarn tails. Insert it in the same point that the yarn tails come out of the piece, and out of the other side of the piece. Tug as hard as needed to hide the knot inside the piece.
