I know, I know. It can be pretty rough. I was not the best thank you note writer myself. We have even had a mail thief at our apartment (not joking) so who knows if my thank you notes even ever got to their destination!!!! AGH.
Anyway, the best thing you could ever do for yourself is to not wait until after the wedding to tackle that loooong loongggg list of notes. If you have a shower, try to get those done within a few weeks. Unfortunately, that is the easy part. The hard part is staying on top of the notes for the wedding gifts coming in as you get closer to the big day. Going back to our very FIRST Tid Bit...write it all down! When you get a gift in the mail, or someone drops it off at your house, just keep a list nearby where you can scribble it down. It may be smart to even write the date that it was received. If you want to get real wild, you could keep a spreadsheet on your computer!
If you have hundreds left after the wedding, don't panic. Just take it in strides and have your GROOM help you! Do something really easy for dinner and both knock out 10 a piece. That would be 20 over with in one evening!
Emily Post has some pretty serious but smart rules, so if you are curious about these standards check them out HERE.
ANNDDD if you are in need of some super cute notes to write your lovely thank yous on...search ETSY! Etsy is one of my favorite places to find unique things for weddings. It is kind of like the ebay of everything crafty, artsy, vintagey, and awesome.
