Wedding invitation help?

have you thought about printing labels? You can find clear ones that you can put thru your printer and then you just put them on the envelopes and they are all done. I did it for some of my clients and they came out fantastic. You can find clear ones in a glossy or matte finish. Some have a very light colored design on them. You can get them at craft stores or even a store like walmart or target.You can also do this for the inner envelope that your guests will send back to you with their rsvp.
