I saw a CASE'd version of this card on FB done in red. As I own the cat punch from S.U. and some heart dies I decided to try this out for myself. I don't know who the original creator was, but it certainly inspired me to try it.
My first card attempt was done completely in black and white, then in red and black and finally I did it in red to give you an idea of the card that inspired me.
Although, I do think the original had different smaller wording on the front and the sorry was on the inside of the card.
I think my favourite is the last black one.
To create this cat in the heart design.
Cut a piece of card stock large enough for the heart die.
Punch out the cat from one side of the card.
Then lay your heart shaped die over the negative/ cut out of the cat and then die cut the heart shape.
The tiny heart is one of the shapes on the owl punch.
