I had to give it a go though, so I made this quick card just to show the idea.
I stamped the heart out 4 times on some lovely bright green card and cut them out. I then used a black Sharpie pen to draw a stalk and cut that out too. Once assembled I think it looks like a 4 leafed clover.
"Good Luck" is stamped on the same green card and some black card cut with Spellbinders Lattice Accents finish it off.
