How much should you sand before staining?
On most raw woods, start sanding in the direction of the grain using a #120-150 grit paper before staining and work up to #220 grit paper. Soft woods such as pine and alder: start with #120 and finish with no finer than #220 (for water base stains) and 180 grit for oil base stains.
How do you know when you’ve sanded enough?
To know when you are done sanding, look at the wood in a low-angle reflected light. Or wet the wood then look at it from different angles. Before you apply your finish, raise the grain by wiping the surface with water. Then sand lightly to remove the nubs from the raised grain.

As a general rule, if you started with 80-grit paper, skip to 120 grit paper, or if 100 then to 150. Finally, sand with 220 grit sandpaper. Note that it is essential to know the type of wood you are finishing before starting to sand as this has a direct relationship to the grit used for final sanding.
Can you stain at 120 grit?
Sanding is the key to a good stain job. Don’t go any higher than 120-grit sandpaper because as you get into the 180, 220, 320 or higher grits you start to sand so smoothly that the wood has a harder time accepting the stain deeply.
