I have recently installed new Marvin wood windows. The trim carpenter came today to finish the window trim on the interior. There are several knots in the wood and it concerns me...even though I am going to be painting it. Isn't detail trim work supposed to be the best pieces of the wood? I understand that baseboards & longer cuts would have these imperfections, but should i be concerned around my windows?

P.S.-there are a few other things that concern me...is this just being petty?
