Tuck the bed as far into the back corner of the room as possible, leaving space to comfortably get in and out. Cover the bed with a tailored bedspread and pillows so if someone catches a glimpse of the bed, it looks more like a sofa.
Review the furniture used in the bedroom to see what can be moved out into the living area. A low chest of drawers, for example, makes a credenza even if it's filled with clothes. Install lighting by the bed on the walls rather than placing a lamp on a nightstand. The goal is to make the living area as large as possible and the bedroom area as small as possible without becoming claustrophobic.
Measure the width of the room. Obtain enough material so that it measure four times the width of the room. For example, if the width is 12 feet, then you'll need 48 feet of material. The 48 feet can be broken up into panels rather than remaining all in one piece.
Measure from the ceiling to the floor. This is how long the curtains need to be. Add in 6 inches to that length so the curtains puddle on the floor.
Hem the top and bottom of the material. Attach the grommets every 12 inches to the material at the top following package directions. Usually, the grommets are pressed into the fabric using a special attachment. If you have a sewing machine with a buttonhole attachment, make buttonholes every 12 inches rather than attaching the grommets.
Attach the curtain rods to the ceiling so they hang down about 2 inches. This gives you room to hang the material. Exactly how you attach the rods depends on the rods. Follow the manufacturer's directions.
Place the shower curtain hooks into the grommets. Hang the hooks over the curtain rods.
