Hi fellow Winter Bride, Im also doing a winter wedding at a ski resort in Vermont. For my OOT bag I was doing the things you listed above but I was going to add a nip of like Baileys or Peppermint Snaps and tie a nice label on it saying for them to add it to their coffee or hot choc. Im trying to do a black/silver with accents of snowflakes here in there Also as guests book I was going to sent them a weekend wedding brochure (made from vista print) with outlines for the weekend. (ie...Fri night welcome dinner for all guests, Sat ceremony time and reception, area attractions, things to do at the ski resort...things like that) Im dying to hear all your ideas as there arent maybe winter brides on here.
