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.  We cannot assign you a specific tree.
