I think I'm a little confused about how invitations from Michael's work. You go to the store and pick out a paper design that you like. They come in sets of 30, so for 150 invites I need to buy multiple boxes. You take them home, feed them into your printer, and print. Is that correct? Do they come with a disc that has a template that you use for the wording and names, or do you just sort of DIY it and hope for the best? If there is a template can you edit the template at all (change the wording for a more nontraditional feel)? Can you chose the style and size of the font? I'm so confused. Thanks for the help!
