I used already made plain cards 5 x5 purchased from Hobby Lobby. Then using Sure Cuts alot, I managed to produce a font close to the star wars. I actually used the mini micro marker cricut adaptor from Custom Crops.com and also used the black marker from Provo Craft for the Cricut. The Star Wars paper was purchased from my local scrapbook store. It started out as a 12x12 page with blocked images. I cut those blocked images apart and divided them up on to the invitations.
**Only word of caution when using mini micro markers is to test your pressure and speed. Mine happened to bleed more then I wanted.
