There really are no ways to completely avoid sandiing after the oil goes on. Always rub carefully and briskly when removing oil that is not staying. Rub it hard. You should wonder if you are leaving ANY oil on when you do it. That action alone will leave the pores with more oil in them. That will reduce the sanding tremendously.

Sanding as a very inexact removal system and seldom the right way to go except for the tiniest final bit of wood removal...

Do not over heat the stock by leaving it in the sun or too near a stove. The air in the warming wood will expand and drive uncured oil to surface where they telegraph like crazy. Doing it intentionally after a number of coats and sanding the tits off will fill the wood fairly well. But the sad fact is that oil will continue to polymerize and shrink over time. The pores will eventually show up again unless the wood is filled.

Epoxy is what I use and it stops the telegraphing.
