Thanks for the suggestions!
I hesitate to give this coworker anything related to alcohol, both because she didn't register for anything related to alcohol, and because our workplace is one where it might feel a little inappropriate. But mostly, she didn't register for anything like wine glasses or anything, so I don't actually know if she and her soon-to-be-husband actually drink.
Re: the possibility of sounding like I'm angling for an invitation...I'd be really
surprised if anything I did read that way to her. Based on what I know about her and the situation in general, I very much doubt my giving her a small token gift will read as anything but me giving my best wishes. I've never even asked her where the wedding is (even though we've talked about it in passing more than once). So that's definitely worth thinking about, but probably not an issue in this case.
Re: ring dishes...that's a great idea. I actually think the one that peaches linked to from Crate and Barrel would be right in line with the type of things she likes (based on her registry), so I will definitely consider that. It is a thoughtful little thing that I hope she wouldn't feel bad getting rid of it wasn't something she wanted, but could be very useful.
Alicia, I agree on the picture frames, or at least agree that you have to be careful. I did get a picture frame from one of my husband's cousins (along with a box that matched it), and while I use it and like it, I've kind of made it fit my taste because the relationship
is meaningful to me. If it weren't a relatively close relation who gave it to us, I'd probably not use it and/or would have donated it by now.
I kind of wish I could make something, but I'm so slow about crafting these days that I don't really want to commit to anything like that, but dish clothes (etc.) are not a bad idea. Someone at work gave me some when I got married, and I do use them. They do wear out after awhile, so it's hard to have too many.
I do also like the idea of a honeymoon gift bag type of thing, though it may require more time/thought than I'm likely to have the ability to put in just at the moment. But part of what made me think about getting her a little token gift is that the topic of her wedding came up today, and I told her that I'd spent my whole honeymoon with a cold because of the sudden loss of the adrenaline I'd been living on for months. I advised her to be sure she packs cold medicine, since there's nothing less romantic than having to find a drugstore the minute you get off the plane on your honeymoon because you're about to hack up a lung.
So, there's a chance she'd be amused but also grateful if I gave her a little honeymoon care package with some snacks and perhaps some kleenex and travel sized medicine.
I also had another thought, that I will consider with all the great ideas you've given me. She has a lot of baking/cooking things on her registry, and there's a local store I really like that has some fun little kitchen tools and gadgets. There are a ton of them of the variety that are legitimately useful, but not the type of thing most people would go out and buy themselves on purpose (because you can easily live without them). Stuff like ramekins, or prep bowls, or other little tools that are nice to have but not at all necessary. I like visiting that store anyway, so I might take this as an excuse to go poke around and see if anything catches my eye.
