For these two cards, I used the same stamp, the same inks and the same colour mat. The difference is that one is stamped on white card and the other on ivory :-)
The image is from Woodware, called 'going to seed', I believe. It's one of my new favourites! The background spatters are a Seth Apton stamp and the sentiment is from Stamping all Day.
I'm not sure which version I like best - they both look very effective.
