Make sure the two heavy gauge wire end from the head have been twisted or wrapped to form a secure neck. Thread the wires between the two body wires. Bend wire in opposite directions, to form a t-shape. Decide on arm length, 1/2-3/4 inches is good. Measure out the arm length and sharply bend the wire with a flat or chain nose pliers. Repeat for second arm. Pass the tail of the are wirm back through the body to secure the arms. Leave ends straight out the back of the bosy to attach wings. You can twist arms to get a spiral texture down the arms.
Legs? If you want, give it a try. I like the clean lines you get with just arms. Besides, legs would take longer and I wanted to finish this instructable as soon as I could :-)
