Pull apart the two halves of your table
Tape together four sheets of newspaper, enough to cover half of the table.
Use a few books to keep
the paper from moving. Now lightly run the side of any crayon around all four edges. This will trace out a thin line showing the edge of the flat part of the tables top surface. (Lightly trace out all four sides of the table half, including the table's center crack.)
