Reeding \Reed"ing\ (r?d"?ng), n. [From 4th {Reed}.]
   1. (Arch.) A small convex molding; a reed (see Illust.
      (i) of {Molding}); one of several set close together to
          decorate a surface; also, decoration by means of
          reedings; -- the reverse of fluting.

   Note: Several reedings are often placed together, parallel to
         each other, either projecting from, or inserted into,
         the adjining surface. The decoration so produced is
         then called, in general, reeding.
