We had a bizarre mystery closet in our apartment that had no door and was right next to another closet. We hid it behind a sheet and started calling it "the bat cave". But for Halloween, I decided it needed something different... Here is how to build your own (temporary and storable) bat cave.
You will need:
--junk fabric, enough to cover your area
Step 1: Building the Cave Walls
Follow the instructions on your dye package. To get this gray color, I only dyed my fabric in the black dye for ten minutes instead of thirty.
Make sure your fabric is rinsed and dried!
