A folder holds paper for this (7)
I believe the answer is:
origami
'paper for this' is the definition.
The definition suggests a singular noun which matches the answer. I also know that 'paper' relates to this answer.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for origami that I've seen before include "Art of crafting objects from paper" , "Artistic paper folding" , "Creation of objects from paper" , "Paperwork, as it were" , "Art originally created in simple materials to design bird forms" .)
