The Hogwarts Express is waiting! With ticket in hand, your guests can travel to the well-hidden Platform Nine and Three-Quarters thanks to this easy DIY from the Judth Fernstrom Photography blog. #HarryPotter
Platform No. 9 3/4 - I taped fishing line to the floor (you have to do both ends or it curls up on itself). Then I slid one piece of paper under the line at a time and taped them. I did them in sections so you could still walk through. Two lines through the middle brick and then I taped the double bricks to each other to make them a little more stable.
