Both use Lavinia heart stamps. I die cut a heart and lightly pencilled round it, the followed the outline using the small heart stamps in a couple of colours, the piled up the dies to give dimension, edging each one, then used the single small heart stamp with glossy accents to finish.
The other card I stamped through the negative of the heart from the previous card with the lavinia heart stamps. Love the simplicity of this. I finished it off with a Martha Stewart word die.
...got another idea now - got to go and try it out!!!
