This nursery rhyme makes an ideal subject for a rug or wall hanging to be used in a child's room  Keep it bold and fill the shapes with flat colors, and it will be finished in the "shake of a lamb's tail".  You could try using natural wool for the sheep.  This is a fun and attractive pattern from DiFranza.
