First thing this morning, we began inserting the boards into the Under Hill garden door. We had left an opening in the top of the welded steel frame of the door. One by one we slipped in the boards and moved them horizontally into position. Using a scrap of the planking, we then tapped the tongue and grooved boards into each other. The extreme amount of welding had warped the door frame a little in places but wth the help of a sturdy crowbar we took care of that in a hurry. The wooden boards look fabulous in place. The garden space was suddenly very private as we had planned.
