This is Dance Legend Thermo Trio, which shifts from a pretty pale lilac when warm, through pink to dark purple when hot. I then stamped over this with Barry M Silver Foil and Born Pretty Store stamping plate BP-48.
I love how this came out, although it was really hard to capture the cold colour, as it's been so warm recently. I'm always really hot at the moment!
The Born Pretty 48 plate is fast becoming one of my favourites. The pattern is so pretty. I especially like the swirly bit on my ring finger.
