Yard Sale HELP!!!!?

I have never had a yard sale. I have went to a few and I know not to put things on the ground....as I hate bending over to look at them. I have bright signs up so that's taken care of it. I really need to know about clothing and pricing. I have everything from shorts/shirts to nice dresses. I don't know what to price them at and also lots of sandals and purses?? Last how do I place them? In boxes on tables? Just folded up on table? I would really like to hang them but I don't have a fence or trees. I live in a duplex type subdivision. Any suggestions about that? Thanks
