We aren't doing personalized anything. Just don't have the funds and I don't believe its necessary for us. No chair covers for us either. Our venue charges too much for them. our STDs we got for a steal, so I can't complain about them. Even our invites were nice, and 50% off, so can't complain.
We are planning on doing wine for favors. To some a waste, to me--it's heaven. I love wine and figure if guests don't take it, the more for us!
I think it's only a waste if it doesn't get used. So before you spend money on anything, just have a good think about how it fits in to your day and make sure you can see the quality. You don't want to spend good money on something, and then it's poor quality or doesn't have a use on the day. I get so tempted when I see "cute" things on sale, like "I'm sure I'll find a use for this at my wedding". But unless I know what that use is, I try to pass.
The one thing I am worried about being a waste is the lawn games. A colleague of mine had them and she said no one used them. But I've had 2 other friends attend weddings with lawn games and both of them said everyone loved them. I guess it depends on the crowd. And I'm not sure how gamey my crowd is. But I already paid the deposit on the vendor, so ... I guess now we wait and see.
The stupid chairs I'm renting that are costing me $1100 with delivery and set up. Our venue has chairs, free chairs. But I couldn't get over how ugly they looked, so I'm wasting stupid money on chairs.
Customized signs- serious waste as well. I will have one (for unplugged ceremony), but I'm making it myself with my cricut!
