What is Wood Joinery?

• Joinery is a part of woodworking that involves
  joining together pieces of wood, to create
  furniture, structures, toys, and other items.
  Some wood joints employ fasteners, bindings, or
  adhesives, while others use only wood elements.
• Joinery used to build a house is different from
  that used to make puzzle toys, although some
  concepts overlap.
