Oriental curtain material (6)
I believe the answer is:
bamboo
This might be a double definition.
'oriental curtain' is the first definition.
'bamboo' can be an answer for 'curtain' (thesaurus). I'm not certain of the 'oriental' bit.
'material' is the second definition.
(bamboo is a kind of material)
Can you help me to learn more?
(Other definitions for bamboo that I've seen before include "Tropical grass/wood" , "Giant tropical grass" , "Tropical grass with strong hollow stems" , "Treelike tropical grass" , "Thick tropical cane" .)
