Name of the piece of cloth or banana leaf used to shape the rim of pottery in Mnong language (Yang Tao village)

Yo khoanh says the name of the piece of cloth used to shape the rim of pottery in Mnong language. They note that before they had cloth, they used banana leaves (ha ju) for that purpose. Using the banana leaf is easier, but using the cloth is faster, so that's why they use the cloth now. Both the banana leaf and the cloth used to shape the rim are called “at”, they can also be called “at dlah”, adding the general terme for pot.
