The 9 3/4 Platform sign (and brick wall) that greeted guests as they arrived at the party was my absolute favorite.
For the 9 3/4 platform sign, I started with a piece of foamcore from the dollar store, I covered it with a piece of red bristol board, and I secured it around the edges with red duct tape. Then, I printed the number and letters on my computer, cut them out, and attached them to the sign. (I finished the sign with a plastic chain I purchased at Halloween... but a piece of twine or ribbon would work too.)
To make the brick wall, I started with a white paper tablecloth (backed with plastic) from the dollar store. Then, I dipped a sponge in red paint, and pressed it onto the tablecloth to make a "brick". I repeated this process until the entire tablecloth was covered.
I also had signs for the different "shops" from Harry Potter. I had one for Flourish & Blotts, one for Madam Malkin's Robes for All Occasions, and one for Ollivander's. I printed them on my computer, and framed them in inexpensive red frames (from the dollar store).
Finally, I made a bright and cheerful sign for Honeydukes Sweet Shop. I started with a piece of foam core from the dollar store, and I trimmed the edges with duct tape. Then, I printed the letters on my computer, cut them out, and attached them to the sign.
I thought these signs were a lot of fun and really helped the guests feel like they were transported to the world of Harry Potter. I loved them all, but the Platform 9 3/4 signage was definitely my favorite. What do you think?
