What is the best way to stain an interior pine handrail to match the staircase?

Colour matching wood is one of the most difficult tasks. It may look the same, but different species of wood can have vastly different reactions to a wood stain, even in the same piece of wood. This is where test areas come into play. Wood stains such as Manns Classic Pine Stain have small tester pots available, helping you to do a suitable test area to help achieve the perfect match.
