This tent is made with a very lightweight cotton gauze fabric. It is still strong and durable but it is very thin and let's the light through so beautifully. It's the same type of fabric that some muslin receiving blankets you may have seen or used are made from. It can be hung outside for a birthday party, special play time or photo shoot but I would not recommend leaving this tent outside since it is not an outdoor fabric.
I have added a little loop that hangs down on the inside of the tent so you could hang a little something on the inside like the paper ball or pompom. They even make lanterns with a battery operated light that I think would be so cute to add a little light on the inside!
