My coworkers (none of whom we invited to the wedding) pooled together and got DH and me an AmEx gift card for $220. I was floored by their generosity. About 10 of them signed the card it came in. Do I write individual thank you notes to them? I want them to know I appreciate it but I am worried about 2 things...1. not repeating myself over and over again (though I doubt people will sit there and compare thank you notes) while saying more than just a thank you because it is hard to say anything about a wedding they weren't invited to. and 2. I can't read one of the signatures on the card! I don't know how to handle that at all and obviously would hate to give everyone but 1 person a thank you note or give a note to the wrong person.
