The best way to put ribbon on a Christmas tree is to start at the bottom and work your way up. Take a piece of ribbon and wrap it around the tree trunk, then loop it around a branch, bringing it back down to the trunk. Repeat this process, working your way up the tree, adding more ribbon as needed until the entire tree is covered. Make sure to evenly space the ribbon around the tree and to keep the ends of the ribbon neat and tidy. And don't forget to add some lights for an extra festive touch!
