Today I made a birthday card in a gatefold style. Thus the front of the card opens both ways from the middle.
I used the Peaceful Poppies DSP as the front of my card and used Basic Black Cardstock for the mat. The Painted labels dies made a great addition using cardstock that coordinates to the DSP. I attached my greeting to the centre of the die cut shape and then adhered it onto the left front only. This makes the card open easily and also serves as a way to keep the card closed.
