Mason Jars. Just think about it for a second. Let your mind wander.....wait! are you just thinking about jam? or pickled something-or-other? You've got to step outside the box here. Mason jars can make some pretty amazing little things, especially for a green wedding. Everybody's got some stockpiled in their basement, and if you don't, I'm willing to bet you have friends/family who do. They are a simple, inexpensive way to do just about anything, from drink glasses, to vases, to wedding favors. All it takes is a little imagination and a little creativity.
instead of regular drinking glasses. Are you having an outdoor cocktail hour? Think about setting up your station with mason jars instead of plain old glasses. They can be fancied up a little bit with colorful straws, tags, bling, or just left alone for a more rustic feel. Paint on a little chalk board paint, and guests can label them with their name, so there's no drink confusion (you don't want Great Aunt Liza mistaking your vodka & cran for her punch).
Because they aren't plastic disposables, you can reuse them, which means
way less waste at the end of the day. Also, they look and feel a lot
better than plastic anyway! And you won't have to rent any glassware if
you go this route, especially if you are having a smaller guest list,
which can save you some cash.
