The card - stamped images and window die cut are all from SU.  I'm not sure why the sky looks so green, but it is actually more blue in real life.  The images are stamped on the card front and then the window is popped up on top.

The class projects are done, cut and bagged and ready for class tomorrow night - whew!  Now it's time to go to the store and get food and get the mess I've made picked up!

Have a terrific day!
