Wood: use thin wood, from 3 to 12 mm. Thin wood (3 mm) is made of plywood: i.e., thin sheets of wood glued together.
The advantages of thin wood are easy cutting and a lighter weight, so that an object can be hung on a wall without nails (using glue paste, for example).
For small-scale projects, a hand-held scroll saw is sufficient. Ideally, however, you should use an
electric scroll saw for cutting wood, with a very fine blade that enables you to make rounded cuts while ensuring
safe work.
