Cling wrap background technique

Had another afternoon playing with different background techniques. This time I was using crinkled up cling wrap as we call it in New Zealand and of course using my chalk inks.
I only have 3 different coloured chalk inks and so at the same as making this card i stamped up another couple of backgrounds with the same technique for future cards.

This is the completed technique again I am really enjoying trying the back to basic techniques just now.
