If it’s very very light, yes. But we cannot, under any circumstances, risk any damage to the trees. So please be gentle with the trees, and use a method of attachment that will not leave a mark or scar the tree in any way. Think cloth – preferably no paper strings, since they will stick or leak color on any tree as soon as it starts raining and that is almost impossible to remove when you de-install your project. Please check with your curator before hanging. Also, many of the trees on Governors Island are large and lack low hanging branches. Think BIG tall trees. We cannot assign you a specific tree.
