To put ribbon around a Christmas tree, you'll need some ribbon, a pair of scissors, and some patience. First, measure out the length of ribbon you need and cut it. Then, wrap the ribbon around the tree, starting from the top and working your way down. Make sure to tuck the ends in so they don't stick out. Once you've got the ribbon where you want it, tie a bow at the top and bottom of the tree to hold it in place. Voila! Your tree is now adorned with beautiful ribbon.
