This is one of the best forms of origami. It requires some dedication and hard work to make a big origami project. Well, spending time folding paper isn't such a tiring work to do at home nowadays.
There are many small 3D origami projects which use under 200 pieces (Can be finished in under a day). There are also projects which could take weeks to finish. I have done a project (a swan) before the lockdown and a daffodil during the lockdown.
These times have helped me in finding a lot of good use for used paper as well.
(The daffodil was done using 1500 pieces and the swan was done using 930 pieces)
