The 7 cards are 5.5 inches square. Invitation and RSVP envelopes were printed. Because we went with a linen card stock, I did have a higher limit against how small I would make the text. Each card design is mainly text- a fun font for the titles, a more basic font for the information- and seashells.
Also because of the linen card stock, I recommended not going with a photographic cover image. The photo cover image -also created just for her project- that we considered using for the invitation cover card was something to tie in with the glossy front save the dates and thank you cards she ordered. The thank you cards (left) glossy front folded 5.5x4.25 inches. Generally for any designs involving photographic and full coverage graphics, people are happiest going with glossy cards.
