Hey everyone,

Our kitchen is separate from our dining room by an island and a 55-inch or so opening.

The dining room (and that half of the house generally) is covered in very old 1.5-inch plank birch flooring, maintained with linseed oil, in pretty shabby condition (tho I say this with love).

The kitchen is going to be covered next month in new 1.5-inch birch, also to be maintained with oils.

So we've got 2 1.5-inch birch floors meeting each other. One is ancient; the other still in its infancy.

We don't want to feather them into each other because that'd be expensive and because we want to be able to change out the old floors in about 5-10 years.

I've thought about a few high-contrast options (some sort of copper band, for example), but I think it may be smarter to do a low-contrast, nearly invisible threshold. What are your thoughts? How would you make a low-contrast threshold between the same wood, at different ages?

Thank you!
