I am a huge fan of Stampin Fabulosity and she has created several great and awesome projects using this system!
I want to create these fun and cool yet chic embossed envelope flaps with it for our invitations....
I am even considering doing a die cut of a chandelier and making a pocket fold type thingie with it...
(Something like the one on the left from Paper Nosh, picture courtesy of Blush Events)
Here is the dicut that I was thinking of getting (the Chandelier uses the same as the cuttlebug which is another advantage of getting it!!)
The inside would still totally have a chandelier or two on them and the pocket fold would be very very simple probably only card stock folded in half something like the Basic Pocket Fold Jacket on the left.

I am thinking of using a silver metallic paper or a blue metallic paper with a black insert for the cards and the invite stamped in the metallic silver I think. I am also thinking of the chandelier matching the inner cardstock color with perhaps a shimmery black or something like that and tying it with a great ribbon.
