I get most of my fabric off base even though the craft store on base is slowly getting more fabric in. The shop I frequent the most has very nice cotton fabric for 525yen/meter. With the current exchange rate of 82yen= 1USD I pay about 6.40 USD per meter. There is one fabric store that has some awesome fabrics but insane prices, 1500yen/meter which is about $18 USD/meter. I can't imagine having no choice but to pay that much. I would be really limited on what I could buy.
