Observatory Trim
All trimming used was plain vinyl siding used mainly on trailers. It is cheap and is easily cut with a scissors or razor knife. Various shapes are available as well as colors. Vinyl trim was attached with common nails and small wood screws. Flaps on the trim conveniently conceal these. If you have a heavy duty staple gun, you can use it to attach the trim.
