A reference on woodworking joint types and their documented use in Polish furniture and structural timber construction.
Cedar & Plain is a static reference covering the geometry, structural behaviour, and historical context of common woodworking joints as they appear in Poland. The three main joint families documented here — mortise and tenon, dovetail, and lap joints — account for the majority of structural connections in Polish furniture and timber building from the medieval period to the present day.
The site does not sell anything, represent any organisation, or promote any product. Its purpose is to collect accurate, publicly verifiable information on a specific technical subject and present it in a readable format.
Content is drawn from publicly available sources: Wikipedia, museum catalogues, academic publications on Polish vernacular architecture, and standard woodworking references. Where precise data is unavailable, the text uses neutral language rather than inventing figures. No statistics are invented; no organisations are fabricated.

The site covers woodworking practice within the borders of present-day Poland, with particular attention to regional variation: Mazovia, Lesser Poland (Małopolska), Silesia, Podlaskie, Pomerania, and the Podhale (Highlander) zone. Where regional differences in joint selection or cutting technique are documented, they are noted in the relevant article.
