Hello: I am interested in creating a "parquet" pattern using wood flooring, probably a crisscross of one wood with another species inset, alternating direction. Would all of the tongues need to be cut off of the insets in order to actually install them into the squares? Should they be separately inset or attached to a backing to make, essentially, a tile? Does anyone have any experience doing this? How difficult would it be for an experienced floor installer? Alternatly, does anyone know of a reasonably-priced source for actual large scale (18"-24" pattern)parquet? Thanks!
