I have really struggled with this theme!
The 'lock' is obviously the keyhole - and the 'key' to freedom is the other side of the door - which you can see through the keyhole
Because I have used metallic paint on a very textured paper - the scan doesn't really show them up properly
The gold paint looks really shiny and rich looking - and positively glows in the light.
The borders are the same thickness which for some reason doesn't show up on the scanner!
Oh - there are some little marks on the glass scanner which look like they are on the ATCs but are not.
One more to go for the set
