For the card I used white cardstock it was a 8 1/2 x 11 and I cut it in half so I could get 2 cards out of 1 paper.
The center strip I cut it at 2in. and the paper came from a pack I got at Hobby Lobby the name is Ella Blue.
The paper with the inital is a blue piece of cardstock with rounded edges and a inital stamp done in black ink.
I also made envlopes to go with these and used my Martha Stewart Scoring Board. I am in love with it, it's a cool tool to have.
