This is one of my latest books. It is made of MDF, is engraved with a dremel, and stained with acrylic paint and linseed oil. The design is based on Celtic knotworki The book holds 150 sheets of paper (300 botrh sides). The inside is lined with felt paper. There are screws that hold the paper in place and can be removed to add or remove pages. Al the metal is solid brass.
The design was done using the software AutoCAD, then printed out and glued to MDF board for cutting and engraving
