Before lurking on TK, I was all about a donation favor until I learned that it comes off as AW-ing (especially using "in your honor" somewhere on the favor). This, among other things, is one of the great things I learned on TK that makes me very happy that I came here to lurk and ask questions.
Anyway, for favors I'm going with an edible, but my FI and I still want to make a donation to the org that we had in mind (ASPCA) mostly in honor of not our guests, but our rescue pup who we love so much. I wouldn't shove anything in our guests' faces regarding our donation (putting a print-out on their place settings, etc.), but I was thinking about maybe framing a picture of our dog along with other photos we'll have around the venue (of us, close ones we've lost, etc.), along with maybe a little blurb letting our guests know about our dog's story with a little tiny piece mentioning we donated to the org in her honor.
Or is that just tacky?
