I've missed this challenge for quite a while but always take a look and would you believe when I saw it today I had almost finished making a card using just this colour scheme. It came about because I wanted to do something using micro beads - I bought a pot in a fit of enthusiasm some time last year and it hadn't even been opened until today. I stamped some swirls onto card, applied double sided adhesive sheet and then the micro beads; found some matching purple card which was punched to match the die cut shape in the centre; stamped a greeting and added a bow and that's how the card evolved from my first experiment with micro beads.
