Where can I get some polyviscose fabric that does not cost 35 dollars a yard?

Also, the only place in town is JoAnns and I'm searching for fabric. I would love to get some fabric from there, for a DIY kilt, but I always get lost in the huge selection fabrics. I keep reading about polyviscose fabrics but I cannot find it at a low cost. I'm frustrated because it seems that the cost for fabric is more than a custom made kilt.

Thanks.
