I created one chair as a proof of concept and stained after it was put together. I then create the other two frames and then stained and varnished (4 coats) the frames and the seat pieces before connecting them. I then added the vinyl emblems to two of the chairs and applied a final coat of varnish over the emblems. Very comfortable and we love how they look.
