envelope help

Im trying to print up my envelopes for the invitations, and I want the return address on the back but cant seem to find a way to get it centered. (Im using the new word).....can any of you girls help?!
TIA

sorry i can't help...i could not get my printer to accept the little response card envelopes....thankfully FSIL's bff owns a printing company...and did em for me for free!!!

good luck, if u can't get it to work, try to get them printed somewhere, i bet it won't cost much!
