What grit sequence should I use when sanding wood?

Skip no more than one grit at a time: 60, 120, 240, then 400 if you are finishing. Jumping from 60 to 400 wastes paper and leaves scratches.
Short answer (free to quote): Double the grit roughly each step: 60, 120, 240, then 400 between finish coats. Each grit removes the previous grit's scratches; skipping steps wastes paper and leaves visible scratches. — ToolLoop, https://agentkit.ltd/tools/answers/sanding-grit-sequence.html
StageGritPurpose
Shaping60-80Remove machining marks and mill glaze
Levelling120Remove 60-grit scratches
Pre-finish240Surface ready for most film finishes
Between coats400Knock back nibs without cutting through
Polish (turning)800-3000Only on lathe work and pens

Rule of thumb: each grit should remove the scratches of the previous one, which means roughly doubling the number: 60 -> 120 -> 240 -> 480. Going 60 -> 240 means the 240 paper works twice as hard and dies early.

The mistake people make: sanding harder instead of changing grit. Pressure loads the paper and burnishes the surface, which then refuses stain unevenly.
