Here is the current inspiration board at TicTacToe Challenges:
For my card, I went with the bottom horizontal row: white, red, glitz/glitter.
I used a Tim Holtz stencil, with some glitter and glitter grab from Taylored Expressions for the music note background. The heart music notes are Taylored Expressions dies and the "love you" is a Cricut cut. I used red shimmer cardstock for all those, along with the card front. One Valentines' Day card is done!
