Would like to buy a roof for it. One because it's under a tree, so leaves and bird droppings fall on it. Two because the kids could use it in the rain with a roof. Three because it could also be a bit like a den.
However, seems there isn't one that fits it. It only has four poles which is unusual it seems and a limiting factor.
Lot cheaper as well to just buy a play parachute but again, only 4 poles might not work and would be a waste of money - was thinking I could attach it to the lowest branch of the tree above but it seems unlikely it would be a perfect fit.
