I belong to an online community of rubber stampers at 
Split Coast Stampers.  They post a lot of stamping challenges, which I like because it helps my creativity.
I recently combined two challenges to make this card:

The first challenge is called Featured Stamper.  It involves looking at another member's gallery and choosing a card to copy.  I chose 
FS42 (TexasGranny) and loved the use of circles on this card.  I then chose a color challenge (
CC143) to decide the colors I would use for the paper and ink.  The colors are Summer Sun, Certainly Celery, and Old Olive.  I love how it turned out!
