I've used a mix of Heartfelt Creations products here (All Glammed Up shoe stamp and die, Botanical Wings die and Botanical Rose stamps)
I stamped and embossed the shoe on a piece of black A4 and then scored it just inside the left-hand edge, before folding the card over. I then placed the die slightly over the fold line, this cuts a shoe-shaped card blank.
It's quite small so not a lot of room to write much inside but it's cute for a little thank-you note or similar.
The flowers stamp and die are genius - you can do six flowers at once, so the actual card is very very quick to make.
