The knitter counts how many times two Evils are adjacent to each other, with Evils being able to count for two pairs if both neighbors are Evil. She can be easily disproven/proven in some cases; if she says there are 3 or 4 pairs of evil, that can not be a false claim due to it being exceedingly rare. Note that the Wretch is considered among these pairs. 

Claims of 4 pairs can only happen in Puppeteer+Wretch games as of now, and it means that all the evils are bunched up around the Wretch in some order, as well as that the Puppeteer did manage to create a Puppet. 

Claims of 3 pairs can either happen in Puppeteer or Wretch game.

Claims of 0 pairs (Evils are not adjacent to each other) can not happen in Puppeteer games, unless the Puppeteer has failed to create a Puppet.

Any claim other than 0 pairs in a game with one evil is False, unless there's a Wretch.
