I made this card for a challenge but it doesn't quite fit the criteria so I'm just posting it here. I did the diamond pattern with a sun ray stamp in a pale dark purple on white cardstock. You can tell I didn't measure before stamping as the diamonds are different sizes. It turned out ok though, as the sentiment (in dark grey) went on one side and the orange 'sun' fit inside the pattern beside it. I used a piece of grey ribbon to cover the not properly lined up reverse rays and mounted the panel on a piece of grey cardstock. To make the sun shimmer a bit I added some yellow glitter glue.
