First you must fix a couple of supports on each side of the room, taking care that they are screwed firmly into the wall, and also taking care not to damage the paper.
If you are a neat workman, you will find on taking out the screws that the two small screw-holes on each side will scarcely be noticed, as of course the supports must be fixed near the ceiling.
You must then put up your curtain-pole, which should be as thin as possible, so that the rings may run easily. A cheap bamboo pole is the best.
Two wide, deep curtains are required; very likely the nursery curtains may be suitable.
On to these curtains you sew a number of small brass rings, which you can buy for about 20 cents a dozen, or even less. The rings should be sewn on the curtains, as you see in the illustration, right across the top, and from the extreme top corner of the curtain, slantingwise across to the middle.
The top rings are passed along the curtain-pole, a string (marked in the illustration A1) is sewn on to the curtain, and threaded through the rings until it reaches A2. It is then threaded through the rings on the pole until it reaches A3, when it is allowed to fall loose.
The same arrangement is gone through with string B. The bottom of the curtain must be weighted with shot, or any other weights that may be convenient.
When the curtain is to be raised, the stage manager and his assistant stand on each side of the stage with the strings ready in their hands, and at a given signal—the ringing of a bell is the usual sign that all is ready—they each pull a string, and the curtains glide to each side, and may be fixed to hooks, put up on purpose.
When the curtain is to fall, the two in charge of it must simply loosen the strings and let them go, and the weights cause the curtains to fall to the center.
