There are many episodes from Krishna’s life that can be used for a jhanki. The most common are the birth of Krishna, and Vasudeva carrying Krishna across the river.
Thankfully, it is very easy to make these jhankis.
Vasudeva’s escape scene
The ground can be any flat surface.
Use sand and grass to make the appearance of a forest. You can also easily make huts using cardboard or origami. Wild animals can come from one’s toys. Small domestic animal toys can be placed outside the origami huts.
For the river, you can line the river using small pebbles, and paint the area within blue. At one place, a passage for Vasudeva can be indicated by painting that part white.

Making the prison scene
Take a small carton and use it to form the basis of the prison. Cut out the windows and doors, taking care to leave cardboard strips to make them appear like prison bars.
You can make the shape of a child out of play dough.
Govardhan Parvat
This is a slightly tricky scene to execute. This will use cardboard cut up and painted in the shape of Govardhan parvat. You can also use play dough to make this. Thermocol is, of course, the lightest material. To ensure that the hill is balanced, use a little flat base that is surreptitiously added to the top of Krishna’s finger.
You will need a real Krishna idol for this scene.

Using existing Krishna idols
You can also creatively use the Krishna idols you do have and create scenes around them. For instance, Krishna with a bow and arrow can be made Dwarkadhish. Krishna with a flute can be put in a scene made of sand, grass, and a tiny lake made of a flat thali lined with pebbles. That way, there can be real water.
