Sorry I can't send you a herbarium on money plant.
But I can surely direct you how to do it.
(a) Cut a branch of money plant along with it's leaves[about 25-30 cm]
(b) Take two chart papers and place one above and one below the branch.
(c) Place the set up on a platform hard enough[ ex. wood]
(d) Place a really heavy object over the entire set up.
(e) wait for 2-3 weeks.
(f) Take out the branch carefully after removing the above paper along with the below paper.
(g) Paste the dried branch on another chart paper and that on a cardboard or thermocol.
(h) This's your beautiful money plant's herbarium.
