Different neighborhoods sell different things and even different years I have been able to sell different things. It's strange. As far as tables, I have used upended garbage cans with plywood on the top, I have used 2 wooden sawhorses with wood on top.....even large upended cardboard boxes.
For the items I am going to display nicely and hope for a better price I even cover the "table" with a sheet to look like a tablecloth and it looks neater and makes the items look better.

For cheaper items like books, I place them all in a box (one layer only) and place a large price that would say maybe "50 cents each or 3 for $1" something like that. Same with small clothing items, or shoes. I often have children's clothes sorted age and sex and type like GIRLS TOPS 3-4 50 cents each.
Everything should be priced...I hate garage sales where I have to ask for each item.

Also if you have very expensive items, keep them near where you will be, or have a companion keep them near them and always in sight, it is amazing what people will steal. I have had people steal dime priced items and then 1 silver earring when I wasn't looking....strange.

Finally, I have people bargaining ridiculously all the time....some actually pick up a giant armful of things and say "$1 for everything." If it is just worthless to me, and they are nice, then fine take it all, I am happy to give it to you. Near me everyone wants it for 25 cents! lol
But if it is actually hard for me to part with, or is valuable I have learned to say "...the price....yes you are right, that is too high, you don't want it, it's ok, " you should see the look on their faces!

****O..and as far as time...like Devinsmom says above.........that depends on where you are also. My gf in PA is having a sale this weekend---it starts at 6 AM and ends at 10AM! The farmers in her area are up at dawn! But in my neighborhood, I am near a jail and a hospital. My sales only start around 10 and I get lots of business around 4-5 when people get out of work. It makes for a long day I can tell you.
