Hello! My fiance and I are getting married next month. Someone bought us a gift off our registry from CB2 but they left their details completely anonymous. I've contacted CB2 and they said that the purchaser did not include any details about the purchaser at all.
What's the etiquette for dealing with this re: thank you cards? We love the gift and want to express our thanks properly, but we have no earthly idea who it could be from and we have no idea what to do.
Thanks!
