Here is the sketch.
And here is my card:
For this card, I cut LOTS of small pieces of some colors of cardstock I picked out. I then put them together on a piece of white cardstock, trimmed it, added some stripes of white cardstock to it, adhered it to the card along with the 2 bigger blue stripes below it and the one near the top, and added a sentiment and some gems. I'm pretty happy with it. :)
