Indigo Leaves: Duong white paper and indigo leaves. Indigo leaves have been used for a long time in the Vietnamese dyeing techniques, now be used by artisans to create paper that is a bit traditionally trendy.
Vegetable Leaves: Duong white paper and a vegetable called "ngot". Nobody thinks that a vegetable can be combined with Goat paper to create very unique paper, but with the ingenuity of paper-making artisans, all the simplest things can be a special material.
