Each curtain was 2 sections of 4ft wide burlap hung at the top using zip ties and safety pins (burlap is super cheap fabric!). They knotted the burlap together at the bottom. It took several hours to hang.
Their back curtain was about 40ft. x 22ft. and they used only one bolt of burlap.
Top: Make sure to add a couple feet to the length of each strip if you plan to knot it at the bottom.
For lighting, they hung 4 edison lamps in between each curtain on dimmers and then lit the black curtain around it with 575 Source4 ParNels to give the appearance that the light bulb gave off more light than it actually does.
