I'm so excited about my favors. I got some beautiful aqua wine glasses at Old Time Pottery for $1.00 each! They will serve several purposes: 1. They will look pretty on the tables. 2: I'm considering putting place cards in them 3. I want to add a little "thank you" tag so people will know to take them. Maybe with some kind of wording like "remember us and the celebration of out marriage each time you have a toast" kinda of thing. 4. They will be functional. Those who drink wine that night can use them.
Re: Wine glass favors
My friends did something like this. They had a barn wedding and had mason jars for drinks. There was a sign saying to take a mason jar home as a favor. I liked how they went with the décor of their barn wedding and I thought they were cute, but I had no use for a random mason jar at home so I didn't take one.
A month later I went to another barn wedding and they had three kinds of homemade popcorn as late snack/favor. I used a provided paper lunch bag to take home some caramel corn and loved that favor.
I think your glasses will be nice but not everyone will enjoy them as a favor and take one home. You could always add an inexpensive edible option if you really want people to have something to take home.
That doesn't mean you won't GET opinions just because you didn't ask for them. That's how public forums work.
