I bought my first little corner punch (yay!), so had to try it out here - I used it at the bottom of the card, and used some left over pink torn paper and glued it on the bottom inside of the card so that the pink shows through the punched corners.
|(I think I put the card a little too far into the stamp, that's why it looks a tad skew here at the bottom).|
And that's my little pink card! :)
