Lining the bowl
After the neck has been glued to the body, the body is lined with paper. The paper acts as reinforcement to the seems of the staves. Five pieces of paper are cut out and line the body, and then two more are cut out to line the tail block and head block. They are glued to the body with hide glue, instrument makers glue, or Titebond. Most luthiers in Greece use an embossed foil paper of various colors. I use hand made, acid free, embossed paper.
The bowl completely lined.
Once the glue has dried, attach your label to the inside of the bowl. Position it so it will be viewable through the sound hole.
