It's easy to make two basic rows to make a little doll!
Use some left-overs in the colours you like.
Make the arms a little bit shorter than the legs.
Bend the legs in the middle and add the arms.
Add a quite long doubble tread (so that you can pick up the doll somewhere) where you added the arms and through the had (a little wooden- or foam ball).
Use "un-knitted" yarn to make hair and draw the face with felttips.
