Need for Speed is the perfect stamp set for a masculine card, I made 22 of these for a team swap last month. I don't know about you but I always find masculine cards the hardest to make. I used the Honeycomb embossing folder as it can look like a tyre tread especially if you use the debossed side.
I used one of the stamps from Clockworks for the image in the top right corner and under the car.
