So this is what I came up with.
It's only small (approx 3 x 3 inch) but it's easy to fill a small card when it's a fairly plain design (see http://mojomonday.blogspot.com/ for the sketch). The base is Vanilla cardstock and I used Almost Amethyst card and ink. The stamps are Kaisercraft (those ones I said I really liked but haven't really used). Embellishments are some recycled gift-wrap ribbon and Kaisercraft pearls and rhinestones. I think if I did this same card again I would clear emboss the butterfly image to give it a bit more shine. It would probably also look good done in black and white with a black or gold embossed butterfly.
