"Though the number of flowers you’ll need depends on how long you want your garlands to be, gather up at least a couple dozen blooms, as well as a needle and thread. Carnations are a good choice because they’re sturdy (and affordable!), but any locally available, not-too-delicate flowers will do. (You can also check out online flower wholesalers for by-the-dozen deals.)
The actual process of stringing a flower garland is so simple that it might even be considered zen (in sum: use the needle and thread to string the flowers together, directly through their middles) but if you’re the type who likes specifics, step-by-step instructions are available here. Sure, you could just plop some tulips in a vase and call it a day, but would that really reflect the joy of finally saying au revoir to heavy coats and wet boots in the hall?"
