I keep hearing fireworks around the neighborhood even though the holiday is over. But speaking of Popping, did you see the new Lawnscaping Challenge? The theme is "don't forget the inside" and all the DT made awesome cards that pop out on the inside. You should really check them out.
Unfortunately I don't have a cool die cut to make those pop out pieces so I reverted back to my college days and the world of model making to fashion a pop out structure of my own. After one practice piece it was a success!
