Step 1: Laminate Wood Veneers
There are many sources of veneer online and at other local plywood and lumber retailers. The main thing to remember is to buy thin, paper-backed, or unbacked veneers. Try to stay away from a phenolic backed veneer since it will show more of black line on it's edge.
Cut sheets in half using an exacto knife. Spread a thin and even coat of wood glue on the back of the two piece of veneer.
Sandwich the veneer together, wood facing out, and clamp together for 1 hour between two pieces of plywood.
Finally, once the glue is dry, using a 180 grit and then 220 grit sand paper, sand the sheets of veneer smooth. The layer of wood on the veneer is usually very thin - be careful not to sand too much.
