Holy cow! I'm going to use this site for every single invitation/thank you/label/stationary for the rest of my life! FREE. This will shock you. This is printable "generator" where you type in what you want and choose your colors and BOOM, printable custom invitations.
The Gentleman Crafter - 'You talk about addictive, this is truly addictive! The thing you MUST remember is to have a fresh stack of cardstock on hand, because you will be pulling monoprints all night long! Trust me! It's like this... "wonder what happens if I do this...what if I add this color....Oh that's cool, but if I do this what will happen." It was an awesome night for coming up with a ton of backgrounds I can go back and use when I need them.'
