There is a lot of this fabric being sold on Etsy in various prints and florals. You can also get it at Dharma Trading Co. (https://www.dharmatrading.com/) in both organic cotton and other manmade fabrics like bamboo, nylon, rayon, etc.

Our company hopes to be offering 100% organic cotton gauze soon, but check us out - we've got lots of great fabrics in 100% Organic GOTS-certified Cotton, 100% Hemp, and Hemp/Organic Cotton blends.
