The request was for a male birthday card and what is more masculine than a cowboy? I CASE'd this card from one on SplitCoastStampers - with a few twists of my own. The sentiment on the inside comes from a retired stamp set but it is one that I just love and fits so well with the horse theme.
Here's what you will need to duplicate this card:
Stamps: Horse Frontier & Happiest Birthday Wishes (retired)
Inks: Bashful Blue, Old Olive & Black StazOn
Paper: Bashful Blue, Basic Black, Whisper White
Other: Antique Brads, circle punches & Festive Paper
