The canopy is intended for a frame with a cupola on top My frame is domed with no cupola I sewed the extra square into to hole in the roof The roof fits ok onto the frame and is waterproof The small amount of overlap onto the wall should have another three inches to it I added a decorative border around the top of the walls to cover the white plastic of the screen that shows due to the roof being too short The black tie down Velcro strips were way too short I made them into rings to which I attached fabric ties that match the privacy drapes These ties attach the roof to the frame With a lot of adaptations the netting walls and the canopy create a very nice outdoor dining space
