When our daughter got married 2 years ago, she and her groom had some inexpensive favors for the guests. There were about 150 guests and they planned their wedding on a very tight budget.
There were two baskets of favors. One basket had 1.75-ounce mylar bags of ground coffee that had a tag on them that said, "The Perfect Blend." In the other basket, there were matchbook-like packets with a single tea bag in them. The saying on those was, "Love is brewing..." They were well received.
