Of course, no house can be haunted without the help of a few ghosts. Hang one in a high corner, from a ceiling fan, or from a doorframe under which guests must pass. Stuff one corner of a large white plastic trash bag with 2 bunched-up trash bags. Twist a neck under the head, then fold the excess plastic skirt over the bulge and twist again, securing the resulting round head with a rubber band or string. Make a fluttering ghost by cutting the bottom of the skirt into long strips. A creepy soundtrack of low moans, wails, and screams played throughout your gathering will complete the eerie effect.Table for Ewww…

The idea of squirting ink on a piece of thin wood might seem increasingly archaic to us, but it sure does look nice when you hold it in your hand. Which is exactly why so much effort has been put into recreating the look of printed paper in electronic form; we all love the experience of paper, but the traditional execution doesn’t align itself particularly well with modern sensibilities.
