Step 5: Hand sew the toy closed
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.
