Packaging And Embellishments: If you're adding embellishments, or you're mailing more than just an invite plus an RSVP card (we opted to mail more info, because of the destination aspect), keep track of the weight of your invitation suite once it's all packed up. Depending on its size, you may be facing more postage fees than a simple stamp will cover. You can get a postage estimate using a kitchen scale and checking on the USPS website. Through the USPS website I also learned that square invites and envelopes cost more in postage, by a significant amount. It's not worth it.
Tips For PUTTING IT ALL TOGETHER _ Paper cutting: The Internet loves to tell you that if you are doing your own DIY wedding invitations, you need to invest in a professional paper cutter, or at least a rotary cutter, along with a tape gun, and the list goes on. You can skip this by ordering paper that's cut to size—always double check to make sure you can print said format of course—and skipping any taped on embellishments. I promise, a fancy invitation need not have three layers of cardstock and the ability to stand on its own.
