Hello, it's Jenny here from Jen's Paper Obsession hosting the blog today.  I'm sharing a card I made that has a window in the front.  I was planning a shaker card but with everything going on inside the window I decided to keep it simpler.  It does have a raised plastic window though.
 I cut a circle in the piece of designer paper and sandwiched the plastic between that circle and a piece of thin chipboard in which I cut a smaller circle.  I also cut the Dream word out of the same chipboard before painting it with some new sparks paint.  The mushrooms were backed with white paper and I cut the read tops and mounted them on mushrooms cut out of white.  I added all my elements and adhered the layers together with a strong double sided tape.
