There are no firm rules when draping garlands on a tree (as long as you don’t create a sausage effect, with branches bulging between tightly-cinched garlands).
Start at the top, stringing less garland, and work your way down, increasing the amount of garland.
Use a variety of garlands — from plain to fancy — to avoid a busy look. For every vertical foot of tree, use about two strands of garland.
