Iron On the Veneer Trim Veneer trim tape is used to finish all cut edges of the doors. In my case I am also using it to finish the door and window openings to compensate for the fact that the doors and windows will not pass completely through the plywood. After ironing on the trim, carefully cut it to fit, and sand the edges gently when the glue has cooled. Make sure the outer edges of the doors are neatly covered with no protruding ends of veneer.
In the photo of the window shown above, you can just see the veneer tape that now lines the window opening, covering over the rough edges of plywood. The window glazing can now be fitted into the window and the interior molding matched to the edge of the window surround. If your molding cannot be adjusted to fit, you can use narrow stripwood to fill the gap in the window sill and match up with the molding. In that case you would not need to fit the window and door openings with veneer to cover the plywood edges.
