Designing 'Keep Calm' Card I

Requirements for a pre-surgery keep calm card:

• Small - ideally to fit inside a wallet/purse to easily access whilst in the waiting room before surgery. 
• No images of eyes/surgery. Could increase anxiety. 
• Include what to think about during surgery - After asking 2 of the viewers who completed the survey, and reading a few online forums, it had become apparent most people fear the process of the surgery. Unlike many operations, you remain conscious and the bright lights, loud noises, and large machines can increase stress levels.
• A colour scheme which promotes a calm atmosphere. (Similar to that in my film. i.e warm pale colours. Light orange/pink/pale purple...)

I will use a credit card for a size template.
I will use pale pink as it is easy to look at, is a positive colour, different colour to credit cards - so easily found in wallet, and a different colour scheme to the safety leaflet - keeping them seperate items.
