Well, just a guess on my part. She says 'not paper pieced' from that and looking at the photos, I'd say it contains 40 pages of instructions on making improvisationally pieced blocks. She also states in the comment replies: "...The description of the tutorial clearly states these birds are made without patterns or templates of any kind. Moreover the tutorial is for making the birds themselves, and not a finished quilt... The tutorial describes how to make a basic bird and offers many suggestions for quilters to make their own unique birds..."

If you have a specific question, I would use the "Ask a Question" hot spot in the upper right portion of the listing and ask the designer directly.
