For some reason masculine cards are a challenge for me. I liked how the green in this paper mixed with the floral. I also liked how the doily shape mirrored the pattern on the green paper. Now, I can imagine, "Doilies, Flowers?? That's masculine??"
Somehow this worked, despite the elements sounding frilly. I think the simplicity of the card, dark elements, and use of geometric shapes made this a gender neutral card that worked well for the male recipient.
