Sane Feb 18, 2005	Take a string, wrap it around the table. Divide its length by pi, then 2.

Winner4600 Jan 13, 2006	I like Sane's way better...
paul726 Mar 04, 2006	Come to think of it, you can find the middle of any item without having to mark it in any way.
MadDog72 Mar 12, 2006	The solution doesn't work for all shapes of tables, e.g. a triangular table. The question should be revised to read "a square table" or "a circular table" or whatever.
MadDog72 Mar 12, 2006	Oh, I'm stupid, I just noticed it says "A circular table" in the title.
jntrcs Apr 07, 2006	tape measurer duh just a long one so u dont mark it.
stil Apr 23, 2006	This is easier than constructing a large circle of paper. Take two squares of paper. The width is fine if it approximates half that of the table. Fold both squares down middle forming rectangular halves. Unfold one square. Take one side that is divided by the fold and place that side's corners at the very edge of the table. Do the same with the other square, placing it so the fold lines of the two sheets of paper cross. The point where they cross is the center of the table.
DEJL Aug 22, 2006	Nice.It should be square.
LeafFan4life Mar 06, 2007	it would be even easier to buy a table which is the exact same and mark stuff on that
hersheyugget Apr 28, 2007	i said use tracing paper and make marks on that
Romono445 Aug 16, 2007	How would you get a piece of paper as large as the table?
Deedee123 Dec 30, 2007	Why would she WANT to find the middle of the table?
