One weekend, I stopped by a fabric shop in Oakland that I read about:
http://www.yelp.com/biz/happy-stop-oakland

Happy Stop – 1132 E 12th St. – Oakland, CA 94606

The place is small, a mess and nothing is labeled, but there’s tons of fabrics…
ALL for $2.00/yard (half yard minimum). Cash only.

I was looking for 100% cotton fabric, but couldn’t find any. Many of the fabrics were soft elastic… probably polyester/cotton blends. They did have a lot of pin strip stretchy fabrics.

I asked the owner if I can take pictures to show people and he said to go ahead. So above are some of the fabrics at the store.
