Cas-tastic Challenges is a color challenge this week: Yellow, Blue & a neutral. I chose this Girly Bear from McMahon Five Designs. The sentiment is so true: Play is really the work of childhood. Learning everything from language to manners to physical skills is a lot to learn in a few short years. The card mimics an envelope with the Girly Bear on the flap. Sentiment to the lower left and a blue metal flower on the right. Add a few blue crystals and you have a CAS card (Clean & Simple).
