Alpana style is used by every caste in Mithila while tantric painting is generally made by those who used to practice tantra . Kohbar is not made in Mundan - upanayan instead alpana style is used further in Kohbar each and every motifs have their fixed places , you can't move them BCS it is believed that they can give evil effect as well . For eg:- Purain Paat in center and hence you can't move that from there. Further Gauri Puja , surj-chandra, Nab-graha , Maanch , Mahfa , baans , Bish-hari , Suga , Naina Jogin have their own fixed places .
Your video is very informative. I really liked the stepwise explanation of the different elements of Kohbar design. Thanks for sharing it. If possible pls share the photo of completed Kohbar design for shaadi. A simple one that can be made for the function. Thanks once again
