Little Lamb, who made thee?
Dost thou know who made thee?
Gave thee life, and bid thee feed
By the stream and o'er the mead;
Gave thee clothing of delight
Softest clothing, woolly, bright;
Gave thee such a tender voice
Making all the vales rejoice?
Little Lamb, who made thee?
The theme is continued in this line, where the lamb’s wool is further described as “softest clothing, woolly, bright.” Very few things sound more pure than a soft, fluffy (“woolly”), clean (“bright”) “little lamb”! 
 
 Note the soft, consonants in ‘softest clothing’ – ’s', ‘th’ and ‘l’s.
