Pallet Board World Map

What you need:
-A pallet
-A hammer
-A pry bar (to separate the pallet boards)
-A saw
-Nails
-Tracing paper
-Tape
-A free online map outline of the world
-A carpenter pencil
-A sharpie (color of your choice)
-Indoor latex paint of your choosing (I went with thicker so I only had to paint only one coat)
-One thick paint brush
-One thin paint brush for edges

How to do it:
-Pull apart pallet boards using hammer and pry bar (note: an older pallet is easier to separate)
-Line up boards in configuration of your choosing
-Saw to desired size
-Nail together using additional boards on the back side (I used 3 – one in the middle, two on the edges)
-Print off world map (for 3 X 4′ project, print at 500%). I used this one.
-Using a pencil, trace onto tracing paper taped together
-Color the back side of the tracing paper outline with a carpenter pencil
-Retrace the front of the paper with pencil, pushing hard so that it will bleed onto the boards (I found that lighter boards showed the trace marks more easily)
-Follow the pencil trace lines on the actual pallet boards using black permanent marker
-Using paint of your choosing, color in all the continents, leaving the marker boarder
-Make any needed touch-ups
