Now I'm not a lover of butterflies at all, really don't like the real ones at all, and I don't use them much at all in crafting. But this stamp from Visible Image is just fab. Here's 2 cards I made this week using it.
Heat embossed with a simple inked background.
3 layer stamping for this one, and heat embossed for the topper. I also added a bit of glitter to this one, but it doesn't show very well on the pic.
