The walnut I'm using for the dresser has some knotholes and portions of some pieces are denser than others. These dense areas are brighter than the rest of the board and stand out after sanding. What's the best way to dull the shine and make them look like the rest of the board? Thx

I suspect what you are describing is the wood fibers are running in different directions, hence, some areas show up as shiny areas and other areas show as "dull" areas. If you have some scrap pieces, prep as normal and oil them, to see if the "unwanted" effects go away.
