Marquetry
From DT Online
Marquetry is a similar process to Inlay but more usually associated with creating pictures from contrasting wood veneers whereas Parquetry uses repeated geometric wood shapes to create patterns (Parquet flooring for example)
See the YouTube video How to Create Marquetry Pictures with Wood Veneers.
