Nearly all of our props were homemade or adapted from dollar store finds with a few bigger ticket items thrown in that we got on the day-after-sale at the Halloween store last year.
Step 1: Brick factory wall
Back to the brick - first we cut lengths of the corrugated cardboard that we would need to cover our walls & wall frame. Then we rollered on grey paint, let it dry and taped it with painter's tape (also from the dollar store since we used about 6 rolls!) to get the mortar pattern for the bricks. Then we rollered on the brownish-red color of the bricks. It dries pretty quickly since it's on cardboard too. Finally we mixed up some greenish brown and some black acrylic paints and distressed the bricks before removing the painter's tape. When it's all dry, just peel up the painter's tape to reveal the brick pattern.
To hang, we simply used a staple gun and two people - you really need two people for that job!
