I used a product like this to make my own badges (not bagges - sorry).

These buttons are round - I did find a company that made them rectangle. I think the size was around 1 1/2 x 3. I then created a powerpoint document and made that size red box. I used clip art and got some great Disney characters. For me and my DH I of course used bride Minnie and groom Mickey. For one of my DBM I used Snow White and for her husband I used Grumpy. For my niece and her husband and family I used all Lion King characters (this was her kids favorite movie at the time). I put the character off to the right in the red box. I used more clip art that said Walt Disney World - in the Disney font and put this on the red near the top of the red box and then wrote Guest of Honor near the bottom of the red box. I put the persons name in the center of all this in white bold letters.
I was able to fit a few to a page, printed it off on my color printer cut the red boxes out, put it in the button and clipped it shut. Everyone loved them and most people wore them while at Disney - even to the wedding.
If I can find some pictures I will post them.
