What is muslin?

This FR treated unbleached cotton muslin gauze is a light, semi sheer fabric. It has a natural off-white colour and a coarse plain weave and is treated with a fire-retardant finish. Muslin originated from Dhaka, Bangladesh. It is now produced widely, and our stocks come from either India or Egypt.

What can I use instead of fire retardant unbleached muslin?
