When I attended the Woodware stamping workshop at The Art of Craft (when I made 3 flower cards) I purchased a Woodware stamp designed by Jane Gill - who was our tutor on that day.
I stamped the image onto card and traced it on parchment using a sepia pen and then did a little pricking and embossing. Jane told me that she designed it whilst on a barge holiday. Something she saw must have given her an idea. It is a beautiful stamp - nice bold clear lines which I love and it will stand on it's own or with colour or with parchment as I have done.
The black mat was a sudden inspiration - I think it works.
