Step 5: Hand Sew the Toy Closed
Using a needle and thread carefully sew the seam gap shut as neatly as possible (the red thread is shown in this picture only for reference, in reality you will be using WHITE thread).
At this point you can stop if you want. EVE doesn't really need arms, and if you don't feel up to making arms you can leave her like this. A perfectly good toy to play with.
HOWEVER, if you want to put arms on, and they are really easy to put on, then at this point you sew on two buttons just about in line with the bottom of the face at the side right over the seam.
