Do you have drapery ideas for a doorless entry between and bedroom and bathroom?

i have found using the IKEA wire curtain rod system (DIGNITET or DEKA) with either a curtain or currently my great-grandma's quilt as the 'door'.

Mounted to the walls & laying horizontally, there's still some space at the top for air flow. You can hang blackout drapes or whatever is the light-blocking or pretty level you want.

I've used this method for the past year for my 'bedroom' in a finished basement, right off the stair landing, and it's worked great. I get privacy, and light-blocking (necessary when working a 2nd job at night), and moderate sound-blocking if my son is watching TV in the other 'room' downstairs.
