To put bead garland on a Christmas tree, start by taking the end of the garland and wrapping it around the top of the tree. Then, begin to wrap it around the branches in a spiral pattern, working your way down the tree. Be sure to overlap the garland slightly as you go to create a full, even coverage. As you get to the bottom of the tree, tuck the end of the garland underneath the other garland to secure it in place. Finally, fluff the garland so that it looks full and beautiful!
