A5 CARDS-front and back ideas

Below are a set of variations, where i have experimented with different ways in which i can extend the design on to the back of the card. i have used the spot varnished band as a way which i can extend another design onto the back of the cards. this will be a nice way i can make the designs for these cards unique. as usely cards designs neglect the backs.

i have used the idea that when you open an envelope the first thing you see is the back of the card, so if i put a design on the back which will link onto the front, it make the card have a more interactive feel to it, which may appeal to the audience.
