The Ace of Spades
When I saw this challenge, the first card I thought of was the ace of spades as I love the Motorhead song. I did do one with spade bokeh but I think I need to adjust the cutout as it didn't work too well so I'm sticking with my trusty hearts. It still has a card link right???
Bizarrely, I've just discovered that the group pool's web address has ace of spades in it...spooky!
Oh, and HBW of course!
