Which material can be a mandala made of?

Stationary mandalas can be drawn on the floor (wood, stone, concrete).

Portable mandalas can be drawn or printed on tyvek, pvc or other materials. The surface must be slippy to allow the feet to turn easily. Tyvek mandalas are very light and therefore a good solution, when you need them for weekly practices in places like gyms, which you rent for some hours. Mandalas in pvc are heavier to carry, but more resistant to abrasion, and can be used also outdoors.
