The background paper didn't need altering as it was just the right colour and had a minimal pattern. I painted some of the corrugated card Polly gave me and ripped it to fit on the front of a folded A4 sheet. Below is the open 'card'. It holds a few extra photo's which were a bit of a mish mash of colours, so best 'hidden'.
Oh and a couple of Prima gem swirls in black, my favourite colour.
