Ok, I'm getting married a week before you and I'm feeling behind too. I would agree that STDs should have gone out already....although I started working on mine in October and still haven't sent them out...I also haven't been working on them since! Hopefully this week I will be able to get on it...I work two jobs full time and the other 6 hours of the day I try to sleep, so wedding planning has been difficult. One of my jobs is overnight, so I spend most of the night on the forum, but it doesn't allow me to work on things like invitations.
Because I am so late in getting out my STDs I have tweaked them a little. I am kind of combining the STD with the invite, and included an RSVP. Most people already have our website and we have a fairly small guestlist, (45 invited, guessing 20 will attend), so people have known about the date and location since September. Once I have a finalized guest list and it is closer to the wedding I plan to send out boarding pass invites, but only to those guests that are coming (to save money and part of the stress of making them myself)...
I finally bought my dress (it's actually my 3rd...ugh), and we have our wedding bands, and I started collecting things for the OOT bags, but other than that, I'm slacking.
Wow...sorry this is so long...good luck with your planning; I'm sure everything will come together!
