Printing Envelopes for Homemade Invites

Okay girls...quick ques. - how do you print on the back flaps of the envelopes (return) on both response cards & invites...can you do that both in Word?

i think so..

i know in ms word i just set the paper size to the size of the envelope, then typed where i wanted it to print, and fed the envelopes through... its good to do a test run on paper first to make sure you have it lined up to where you want it..

i will try it
now that i finally found a venue i am starting to think about the invites!!
since i am on a budget - i may make them...
