Not only can they be used as last name monograms, but also as the bride and groom's first name, table numbers, or cute messages. They also can be used to cover frames or pots holding plants, flowers, or table centerpieces. There are also a variety of ways to display and hang your letters. Here are some uses I really love.
There are quite a variety of ways to utilize moss into the decor of your special day. I wouldn't recommend going over board with this though. Pick a couple of different ways to incorporate moss and go with it. It's such a nice touch.
