An arched window panel with "Ibis" & "Cattails" reflecting and looking towards one another. The install posed a different type of a problem due to the fact that there wasn't a shelf or sill to mount the window on. *see photo below. Using a 2"x 2"x 4' piece of "Fir" I customized a permanent window sill that matched the metal window mullion. The diagonal window inserts that are installed into and in-between the existing clear glass had to be incorporated into the design.
