Examples of creating texture with filler varnish (I use Deft) through scraping along grain lines and replicating craqueleur.
Often it looks a bit too sharp before the retouching and the texture might not be identical but it is surprising how effective it is at distracting the eye from that area of repair.
This is what makes all the difference and takes more time than the retouching.
