We enjoyed the Topsy Turvy but were very disappointed after it fell apart after the first season. I took canvas backed vinyl wallpaper and sewed a new cover using the previous cover as a pattern. The pop rivets pull out and a hole punch may be used to make holes for the rivets and drainage. If a pop rivet breaks in removal then use a small metal screw, washer and nut. They have reinforced plastic tarps that can probably be easily sewn. I think it is heavier than the material from the Topsy Turvey.
