This Instructable shares my hard-learned knowledge about how to print and assemble wedding invitations. All you need is an army of minions, opposable thumbs, and patience.
Step 1: Acquire paper
You will need some sort of medium on which to print your wedding invitations. I chose to have a 3-layer invitation, consisting of vellum, regular paper bearing the words, and a larger sheet of handmade paper. I got the vellum and the handmade paper as part of a invitation kit, but needed to add the middle layer when I learned that you cannot print on either vellum or handmade paper (according to Kinko's and Staples.) My paper measured 4.5" by 7.5" for the vellum and printed paper and 5.5" by 8.5" for the handmade paper.
Step 2: Print words
With the size of paper I used, I was able to print 2 pages landscape-style on each piece of paper. You are going to have to trim the paper anyway, so might as well save some trees when you can. Arrange your words and print multiple test copies and get everybody to proof-read. When you are sure you are ready, make your copies using any copier to which you have access. I printed mine at Kinko's, because they were willing to trim the paper to the exact size I wanted.
Make 10% extra, since it is easier to do invitations in bulk.
There are many etiquette sources which can tell you what you should print on a wedding invitation. I chose a contemporary wording:
and Brad Doe
Together with their parents
Invite you to celebrate their marriage
