For some small flaws I've repaired, rather than mix the sawdust with glue, I've mix it with shellac or with the finish I'll be applying.

Color me confused. If I mix sawdust with glue (what kind, BTW?) to fill
a hole, have I not created a spot that won't take stain or even finish?

That's the idea behind the sawdust. It's supposed to take the finish
the same way as the surrounding wood. Well, that's the theory,
anyway.

I get that. But if I get a fingerprint of glue on my project, that area will resist the finish, won't it? Can someone explain what's different about mixing sawdust with glue? Why does the sawdust take the finish in that case?
