These three cards use steampunk jewelry ... nothing new for me, I did feminine cards a few years ago using jewelry.
The first card can be used for any "love" related occasions because it holds the key to one's heart. I started with a simple size A2 card and then ran some wood patterned tape edged with copper tape. The image was stamped in sepia ink and then colored with metallic water color. The key was silver and I colored it with permanent dark brown ink and it was surrounded by gold color rhinestones.
The second card started with an embossed clock pattern on silver paper with a stamped clock panel added at the bottom. At the top I added a sticker tag with a sticker text. The watches are again from the steampunk jewelry counter ... I added a silver chain sticker to each and the some black rhinestones.
The third card is just a fun nautical themed car starting with a white A2 card covered with a wood patterned paper. Next I create a "pirates" map by stamping a nautical image of a ship and compass; which I over stamped with a distress pattern before I embossed it with a world map image. To finish my pirate map I die cut the stamped panel with a parchment die, edged the entire panel with black ink. To finish the card I added a anchor with chain also from the steampunk jewelry aisle- note that the chain is only fastened at either end to allow some movement. Finally I added half pearl rhinestones to simulate bubbles.
There you have my version of "steampunk" masculine cards.
