How you introduce your guests to your house sets the tone for the rest of the evening.
The Hogwarts Express signage
To put this together first start by printing the below signage onto A3 paper.
To make it 3D, the signage was sliced down so just a bit of white border was left, and the signage attached to both sides of foamboard.
To finish it off, a long pieces of square balsa wood were attached around the whole border of the signage, both sides, and painted with gold paint.
To attach it to the wall, a metal frame (from memory originally supposed to be shelf support?) was attached to the signage, using a foam sticky tape (serious hardcore holding ability). A hook took the majority of the support, and the foam tape held the metal frame in place.
The 9 3/4 signage
The second piece of signage is the 9 3/4 sign, which we placed at the front of the property into the ground.
For this, print the below signage
Attach to black foamboard (glue tape works well) and cut out with an x acto knife.
Attach the foamboard sign to a second metal frame, first with a strip of foam tape. Then to make sure it was solidly attached, I ran black fabric tape around as a strip that attached the foamboard with the metal frame so no wind would knock it down.
Use first foamtape, then wrap with black fabric tape to a black wooden pole.
