Sand and paint the wooden palettes. Let the pallets fully dry
Lay the four pallets together on the floor to form a square. At each middle point of the square where the pallets meet, place a C-clamp to hold the parts of the stage together. You now have a stage.
Roll in your long clothing racks and place them around the stage. You should have one clothing rack in front of each outward-facing side of the pallets.
Place your shower curtains on the racks using the snap on rings. To the furtherest right shower curtain ring of the left curtain facing the audience, tie one piece of rope. Run the rope through the other rings to the left so you can pull on the rope to open the curtain.
Mirror the procedure in Step 4 with the curtain on the right. You are now ready for the players.
