A favorite image of mine is Nature's Greeting Deer by Pickled Potpourri. It makes a great male card for a birthday or Father's Day or even just thinking of you. I've cut out the image with a Spellbinders circle die and inked the background with a sponge. I've used woodgrain patterned paper for the card background and added some burlap ribbon and a multi-colored brown ribbon. It is a simple card but shows up the image well.
Pickled Potpourri has lots of nice images. Visit them and see which ones you like best.
