Invitations weren't all that important to me, and I needed to get them out fast due to booking deadlines for our cruise. I would of like to of gone a little more DIY, but I am happy with how they turned out for what they are. I bought two boxes of Martha Stewart invitation kits using Michaels 50% off coupon and then bought colored cardstock to print our cruise information on. I printed the cruise info at Staples for less than $3 and then printed the invites on my home printer. I was going back and forth on whether or not to do STDs, but for my situation I think this was the best route. The kits came with RSVP cards and envelopes, but I will use them as thank you cards, because I chose to have guests RSVP through our website.
