01 · NO-DRILL CURTAIN
Use a tension-rod curtain for a soft bedroom boundary
A curtain is the calmest place to start when the goal is visual separation rather than a new wall. A tension rod can work between two side walls or inside a wide opening, then disappear into the room when the curtain is open.
Styling note: Choose a floor-skimming curtain in linen-look or lightly textured fabric. A warm neutral lets light pass through while still giving the bed its own moment.
