Since i do photography (& graphic design) I wanted to incorporate that into our gifts at the wedding...i am going to do a set of blank notecards with envelopes with some beach scenes I've taken near our wedding location...
I also had a sample post-it note made by VistaPrint.com using the graphic from our invite.
I bought vellum envelopes to put them all in, will wrap them with blue raffia and have a hangtag off of that with the guests name for seating...what do you think?
EDIT: (the post-it isn't huge compared to the cards the way it looks here..haha...it's big so you can see the detail)
