When making Halloween props my 2 goals are;
1: It has to look big
2: It has to disassemble and fit into a small space.
This fits the build perfect! It's the size of my garage door and when I'm done it fits into a bag to be stored into the attic.
OK let's get started!
Step 1: Tools and parts
Med paint brush
White Styrofoam installation panels (found at your local hardware store)
Magnets of your choice (I used ones I found at the local hardware store)
Large letter stencils
Grey spray paint
Black latex paint
Step 2: Building It
Once the glue has dried turn over and use the grey spray paint and lightly "dust" paint. (if you go heavy the foam will start to dissolve) Once dry keep "dust" spraying till you get the desired coverage don't forget the edges, Let dry.
While you wait for the paint to dry you can use this time to come up with names or sayings for the stones.
Once the grey paint is dry lay out the stencils and use brush and black paint and dab on the paint. If you load it on it may take longer before you can move on to the next letter so be careful.
