You can use these twinkle lights, which hang from a cord suspended between two poles, with Grimm Ground or even the Land of Whyst if you want to give it a Hallwe'eny feel. Of course, if you want to put them in your indoors furniture room, that's fine too. This light show sits parallel with and just in front of any Whyst or Grimm wall or they're fine alone setting their own trendy boundary.
