A free tutorial for shirt card can be found here
I'm getting organised earlier this year for Fathers Day in Australia (September 7th), with a shirt card.
This card would also work great for a male birthday or even retirement card. Maybe it's the paper I used in my card but it also reminds me of a bowling shirt.
Stampin' Up! materials used:
Cardstock: Old olive, whisper white
Punches: Small tag (retired)
Accessories: Old olive brads, polka dot parade designer series paper
Other: Computer front for Happy Fathers Day
