Critter Costuming: Making Mascots and Fabricating Fursuits by Adam Riggs (Nicodemus)

I just bought a copy (shipping now) and it looks good. 4.5 out of 5 stars.

This is a great book on making Fursuits, I used a lot of information from it when I made my Fursuit back in 2008

There's a book.

Critter Costuming: Making Mascots and Fabricating Fursuits

• “Critter Costuming,” by Adam Riggs.
  
• “Mordrude's Monster Manual,” by Sarah Wilson.
  
  Unfortunately, neither of those two books fit your description, perfectly.
