I made this pair of folded scalloped oval note cards by setting a Nestibilities die slightly over the folded edge of a 4.25 by 5.5 card base. I used two smaller oval Nesties to create my central panel, which I stamped in colors that coordinated with the patterned paper I used for the card.
I decorated the inside of the card with a spray of the same flowers stamped along the right lower edge.
I got the idea for these cards from some round note cards that were made by Maria Levine, which you can see here:
