yarn technique for arms and legs

 
we need:
 
a strong yarn
a long needle
some pin needles
fix the arms with some pin needles on the right position. Then take away the arms and let the needles on the fixed position.
 
now prick with the long needle in the left upper arm from the inside to the outside (see left picture) and after that shift about one stitch and prick in the upper arm from the outside to the inside (see right picture)
 
now prick with the needle in the left side where the pin needle is
 
and come out at the right side where the other pin needle is placed
  
now prick with the long needle in the right upper arm from the inside to the outside
 
and after that shift about one stitch and prick in the upper arm from the outside to the inside
now prick in the same stitch on the body you came out a few steps before
and come out on the other side in the same stitch you began
tie the yarns strongly so that the arms fit good and strong on the body. Knot the yarns together and sew up the yarnends neatly.
