Take the wool Look into the servers See the world full of dust Poison that surrounds the outside air You can dare to go outside If you just dare to question the truth
Knitting is the main symbol inside the book. Every title is a knitting turn that has to do with the plot. The Unraveling was when the uprising started.
"... She always chose carefully, for proper gauge was critical. Too small a needle,and the knitting would prove difficult, the resulting sweater too tight and restricting. Too large a needle on the other hand, and it would create a garment full of large holes..." (Howey 43).
The outside world was shown to be glum to keep the people outside. When outside, the world looked clean, but it was an illusion created to give false hope.
"A seed of hope caught a taste of moisture. Some wishful kernel buried deep, where he was too late to acknowledge it lest it poison or change him, began to sprout..." (Howey 224).
Wool is a story full of many symbols. The five titles are Wool, Proper Gauge, Casting Off, The Unraveling and The Stranded. All of the titles have knitting context to them.
