As a decoration or as you want to make series of a big banana leaf, a print of it in plaster should make you happy :)
Step 1: FIRST, LEARN HOW TO PREPARE PLASTER
Plaster should be mixed with water in same proportion 1/1 but you can mix it just putting first water in a recipe and add slowly the plaster powder until the plaster can't be absorb by the water. Finally mix and use !

The leaf cutted on the banana tree is immediately posed on a flat marble and we use liquid plater on it.
