I'll admit it up front, masculine cards are really hard for me. Since the men I know aren't in to buttons and bows; I had to step far, far outside my comfort zone and keep this pretty free of embellishments.
Here's my card:
I combined a whole lot of challenges ~
The sketch (that I tilted a little for a jaunty, mischievous effect) is from The Sweetest Thing
Crazy 4 Challenges has a Valentine Theme Challenge as did Quirky Crafts.
And Tuesday Tagger has a Valentine's card for a friend theme.
Easy Craft Projects and Our Creative Corner also had a Valentine's for Men theme.
I used an image from the Cherry Bomb set by Bombshell Stamps as my main image.
