I used Valentine Eris (minus her buddy) to be my focal image on my box lid. I made my box with some brown pearlescent card using a piece 16cm wide by 29cm tall. You can find the instructions HERE This is a great depth of box, perfect to hold chocolates or even a big cookie!
My heart is from Spellbinders, the little heart being from the centre of the big one. The banner is a little date stamp type stamp I picked up in a local junk store for $4 (4 stamps with 12 sentiments each) I finished it with some little punched flowers.
