LOCAL PRINTING: When it comes to short run printing, the local option is my favorite option. Local print shops may not be able to match the price of many online vendors, but you get to have more of a hand in the process, and therefore a little more control over the end result. Some will even let you bring in your own paper, and most will let you use their paper cutters for free (sometimes even if you haven't printed anything through them). Unfortunately, not all local shops are created equal—some FedEx Office shops are great, others not so much. You'll need to do your due diligence to find a good match. InkerLinker is also a good place to find amazing, non_FedEx print shops near you.
Buying/Finding A Design: If you don't have design experience, and you're not fond of pushing images and text around on pages (aka, does the idea of designing a flyer for a Bake Sale or some other event excite you, or does it make you hide under your desk?), you're going to need to find someone to design your DIY wedding invitations for you. Fear not! Thanks to the Internet (and Etsy, bless), there are tons of places to get an invitation design. Some are even our sponsors! Here's a short list of places to check out.
