New cards: Masking...

Last week a new challenge was published @ Scrappy Hands: Masking technique...
I didn't take part of the first week, but I decided to do so now.
I created 2 cards, similar colors, stamps & technique.
Once of the positive & once for the negative.
First, I cut a heart on a cardstock, same size as my card base.
For the first card - I put the outside of the heart and stamped inside... When I removed the outside - I got the heart shape...

For the second card I did the opposite:
I took the heart itself and stamped outside of it.. Creating a background ...
The ladybug is popped up..

Thanks for looking :-)
