Oh also, if anyone wants a good tip about invitation printing services, check out
catprint.com . I designed all of our paper materials (invitations, envelopes, RSVP cards, programs, menu cards, place cards) myself using a free trial membership of Adobe InDesign (lol) and then I had them printed on cotton stock at catprint. They are a small, locally owned print shop that fosters pets in their office and they do amazing quality work. I cannot say enough good things about them as a company.
And if you donate to their local cat rescue, they'll give you a discount! (it's a little hidden, but click around to where it says "catprint cares" and you'll see the offer)
