Agree! the OP's repeat is too small, and so, it doesn't give much variation and why you are seeing it looking so much alike.
The fabrics posted here are great examples.
Although, I'd be hesitant that the black one may have too much black in the background .... though it may be very interesting. Love the yellow one!
Use two mirrors, to help predict whether a fabric will work for OBW.
