My venture into making the palms entirely on my own from scratch seems to have worked.  I wasn’t sure going in if it would.  The trunks were made by taking a 1/4″ styrene rod, chucking it in a drill, and spinning it slowly while holding the sharp edge of a jeweler’s file against it as it turned.  I then painted it with Rustoleum “Sandstone” textured paint and gave it a wash of India Ink and alcohol.  The fronds were made from Oracal peel and stick vinyl cut on a home craft cutter.  The fronds were painted Zinc Chromate primer and then given a wash of a darker green acrylic craft paint.  The dead fronds were painted with a beige acrylic craft paint and then given a wash of burnt umber.
