This is a card I made recently for my best friend, Jenny.
I used plain white A5 card stock which I folded in half lengthwise.
The hedgehog and mouse stamp is a Penny Black design called Merry Band.
I also used a couple of stamps from the 'Think Happy Thoughts' set by Stampin' Up!
As I was making it, I debated whether or not to colour in the mice and hedgehogs, but realised that if I coloured one, I would have to colour all of them, so I decided to leave them as they were. I think it looks rather effective.
