The Spring Fling Cyber Crop has started on Thursday the 10th of September at Scrapbooking Top 50! It kicked of with some fun and games and a Mystery Challenge which was a card with a recessed window. Instructions can be found here: http://www.splitcoaststampers.com/resources/tutorials/recessedwindow/
Here is my take on it.
There was also a Mini Mystery Challenge. You had to make your own paper embellishment from scratch. I made a butterfly and used it on my card!
