Best way to fill these gaps?
We're at the tail end of a den renovation; next week we will install moulding. I noticed today that we're going to have some rectangular gaps between the door jambs and the new hardwood floor if we use the same 1/4" reveal that's used through the rest of the house (or, in some cases, even if we don't). The floor was installed after the old base moulding and door casing had been removed.
Is there a good way to address these gaps? I'm willing to even use big chunks of wood filler putty or something if it will retain its shape over time.
