Marquetry is the process of decorating an object's surface by cutting and fitting together many pieces of thin layers to create an image. It's often done with veneers, or thin sheets of material like hardwood.
Triquetra (/traÉªËkwÉtrÉ/ ; Latin tri- three and quetrus cornered) originally meant  triangle  and was used to refer to various three-cornered shapes. It has come to refer exclusively to a particular more complicated shape formed of three vesicae piscis, sometimes with an added circle in or around it.
