Parashah Korach

G‑d tells Moshè to take a staff from each of the twelve tribes, with the name of each tribe's prince written upon their staff. Another staff was taken to represent the tribe of Levi, and Aaron's name was written on that staff. These staffs were placed overnight in the Holy of Holies chamber of the Tabernacle. Next morning they were removed, and miraculously Aaron's staff had budded with almond blossoms and almonds. This was further proof that Aaron was G‑d's choice for High Priest. 
G‑d commands Moses to return "Aaron's staff" to the Holy of Holies, where it is to remain for perpetuity.

We took 12 wooden stick, painted brown to make the 12 Shevatim rods.

Take one of them to make Aaron's one and cover it with a chain of tissue flowers to make it "blossom".

Make a magen David shaped rod for the sticks with air dry modelling clay. Color the place of each shevatim stick with a different color on the star and make the 12 holes with the wooden sticks. Let it dry.
