Install the circle curtain rod above the bed by using screws and a drill. For an extra degree of security, predrill the holes and insert screw anchors before attaching the circle shower curtain rod to the wall.
Measure the distance from the curtain rod to the floor.
Measure the circumference of the curtain rod, multiply by 2 and then divide it by 4.
Cut four rectangles of fabric that match the measurements you found in steps 2 and 3 using a pair of sharp scissors.
Hem both long sides and one short side on each rectangle by folding the edges down twice, creating a fold that ¼ inch deep both times and sewing them flat.
Fold the unfinished edge of one rectangle down, creating a fold that is 2 inches deep, and iron it flat.
Slide a strip of fusible interfacing that is as long as the short edge into the fold, and iron it in. This creates a firm top edge.
Attach curtain clip rings to the fused edge of the rectangle, spacing it so there is one every 4 inches.
Repeat steps 6 through 8 for the other three rectangles.
Hang the fabric rectangles from the shower curtain rod and spread the fabric around and over the bed.
