I have no financial interest in saying so, but if you're making your own invitations or stationary, I thought I'd pass this along. Joann Fabric and Craft Stores is running a sale on supplies to make your own weddings or special event invitations, programs, etc. Discounts running a whopping 40-50% off! Check it out.
Food for thought: my wife and I made our own invitations those many moons ago when we got hitched. We priced out stationary services and determined that we would have spent about $500 for invitations, programs and thank yous. We wound up rolling our own, so to speak, and spent $200 on supplies. What should not be discounted is the amount of time and ink expensed to undertake such a project. Back in the day, it made sense for us as broke college students. A young couple of working professionals might be better served outsourcing the effort. However, this is definitely an area where costs can be dramatically cut. Far more memories will follow your photos than your stationary from the day, just sayin'!
