I'm going for an exotic look... so to speak... in this room, so I used a gold sari and with a contrasting black and cream fabric.
All you need is fabric, and two curtain rods.
Measure for the length of your front panel. Cut that piece off and flip it, then sew it back on so the pretty side will be facing out when you drape your fabric over the rods.
Hang the rods from the ceiling above the middle of the bed and against the back wall, then drape your fabric over it.
See, super easy!
