Where can I get free material samples?

Hi. I’m an interior design student and I’m just wondering if anyone knows of any places where I can get sample materials? Somewhere in/near Santa Monica, San Fernando Valley, Hollywood, or any other city in or near Los Angeles.
I know the PDC (Pacific Design Center) gives students free samples. But is there any other place that also gives students free samples?
I would prefer specific names of store.
Please and Thank You.

If you contact some area fabric stores they might have some discontinued samples to give you.
