I think the Old Olive and Night of Navy make this card perfect for a masculine birthday card. I used post it notes to outline the border of the stamped image for a clean border and sponged the background.
To make this card I used: (all Stampin Up!) Paper: Night Of Navy, Old Olive, Whisper White Ink: Night Of Navy, Tempting Turquoise, Old Olive, Basic Black Stamps: Lovely As A Tree, Teeny Tiny Wishes Accessories: brads, post it notes
