I found the "Go Green" challenge for March over on Art with Heart.
Here is what I came up with.
So, the first thing I thought of was a frog for green. I checked out the cards I needed to work on for Card Lifters. After seeing this one below; which as for week 8. This card was found at http://www.leiphartonart.blogspot.com/. My son popped into my head. And it is totally something I wouldn't be surprised to find in his pockets!!!!
