What is the timeline ettiquette for writing thank you notes? I know technically you should send thank you's as you receive gifts, but what is the grace period?
We just got an email from FMIL that our first gifts off our registry arrived (we are having things stored at her house). I wasn't expecting anything this early (shower invites haven't even gone out) and I don't have Thank You cards ordered yet. I was going to get Thank You cards in time for the shower (in April). Is that too late to send a Thank You card for a gift we received in February?
