While traveling in couchettes and sleeping in hostels, I realized that a lot of them lack a very basic amenity — a curtain for privacy.
Is it possible to buy a portable curtain that you can easily install in a couchette/hostel bed? Ideally it would come with suction cups, velcro attachments and normal hooks for maximum coverage of grip surfaces, as well as a light-weight black curtain.
Unfortunately I couldn't find anything on Amazon/eBay/travel blogs. Perhaps I missed something and it's actually up for sale?
