Here's a sea themed/masculine card that I made the other day.
The coloring page comes from here, and the word art I did on my computer. I added some sea themed beads that my friend gave me a while back - matted the image on red and brown paper. Eyelets hold these layers together. I mounted the main image on blue cardstock with small checked paper in all the corners.
Simple, fun, and not in the least bit girly!
