First, apply Polyvinylacetate (glue) to the spines of the books.
ALL the books.
Then, prepare the wraparound sheets.
Lay the book carefully in the wraparound sheet.
Make sure it's on the edge.
Lift the wraparound sheet.
Hold it tight against the edge.
Pull it down to the other edge.
Use your folding bone on the spine to seal.
And use the bone on the front and back too.
Do not fuck with us.
When you bind books, you generate piles.
The first proof.
Tapes for sewing multisection books.
