I came across this unpainted real bamboo beads curtain the other day.
It's made of natural stuff (not plastic) which gives it a great look. It is hooked together using steel wire and constructed in such a way that you can cut off the length you don't need and the rest of the beads stay securely in place.
This will be a great choice for those who want a stylish curtain with a different appearance for use on either doors or windows.
I like the fact that it is very well constructed and provides a barrier and some shade while letting plenty of air in. Plus it looks great too.
