In the end I came up with two cards that suit the challenge, but the card below is my entry:
I added a bit of spica pen to the sparkly spots in the tiara. Click on the image to see it close up.
This is also my first attempt at photographing with a coloured background (Simplicity style) and I like it!
Size of card: 3.5" square
Card/paper - Quill white cardstock
Stamps - Cre8tive
Ink - Versacolor "Cement" and "Orchid"
Extras - Spica pen
Tools - Fiskars paper trimmer
Thanks for looking!
