Eight Feet of Fringe
The extra length is the reason to choose this size over a shorter curtain. In a room with high ceilings a short panel stops halfway down and looks stranded; this one reaches the floor or pools slightly against it, which is what makes a doorway read as an entrance. Whatever is left over at the bottom comes off with scissors.
Doorway of Purple
Hung across an opening, the panels become the way into the party. Guests walk through the fringe rather than past it, and the strands fall closed again behind them. Two panels together fill a standard door frame with a slight overlap in the middle, which keeps the room beyond out of sight until somebody steps through. Flat on a wall, the same foil does less.
Layering Two Panels
Hung one over the other on the same patch of wall, the fringe doubles in density and stops any paint color showing between the strands, which matters for photographs taken close up. Placed side by side instead, the pair covers about six and a half feet of wall. Either arrangement takes a minute, since the sticky header is already fitted.
Wrapped for Next Time
PET film at 23 microns and 0.4 mm thick does not shred when a panel is pulled down, so the curtains survive being packed away and brought back out. Gather the strands, wrap them around the header and store the roll flat. Bring fresh tape when they go up again, as the original adhesive will not hold a second wall on its own.
