Instead of licking tens of thousands of envelops for your save-the-dates, announcements, and invitations use stickers! You can take a couple different routs on this one. You can print your return address on labels and secure the envelops with those. Another option is to pick a sticker that has a pretty design on it to seal the envelop. The last option is to use a wax seal to close the envelope. This makes for a more secure closure and it is a quite fancy way to seal the envelop. Wax seals are almost vintage in nature. Not too many people use them, which makes them unique. Plus, it just looks wonderful!
