This technique is called Tea bag folding, which I have created here a simple combination of 8 tea bag folded pieces in various coloured Designer Series Paper.
There is also another unique and exciting technique that I did on the clear buttons. I stamped a definition image from the 'Define your Life' stamp set using StazOn White Opaque Ink. All available from Stampin' Up! What a beautiful addition and simple effective techniques coupled together to create a striking card. Personalise with greetings and sentimental sayings etc.
