Soo i just got my envelopes from PWP....horror story just to let you know...they sent me my invites 3 weeks late!!

anyhow i dont have time to take them to a calligrapher for the guest addresses...i want to just print it on my printer does anybody have a program they use??? or a margin size??
i have no idea how to do this!!! TIA

Obviously do a trial before you mess up your real envelopes but this is what I did for my STD's:


Go to Microsoft works task launcher (usually this software comes on all computers)

Up top click on TEMPLATES

Click on INDIVIDUAL ENVELOPES

Click SINGLE ENVELOPE

Them an envelope sizer should pop up just measure the height and width of your envelop and then click the size on the pop up. If you don't see your envelope size listed then go to the bottom it should say 'Custom size' you can just click that and then put in your own measurements

Then just start typing away! Make sure when your typing the address is centered! GL!
