Swapping couch with Recliner - how to fill holes in floor

Depending on the size of the holes, you may be able to fill them with an epoxy and then find a piece of flooring that nearly matches your flooring and make plugs to fill the holes, as they would in furniture making. Just a thought. If done with care, the grain could align and be nearly perfect without sanding or finishing of any kind. Hope this may help, Happy Trails Bert
