The wax is usually applied by hand to the heated surface of the
iron. A much better and handier way is to bore five or six holes
in one end of the ironing board to a depth of half

its thickness, filling them with wax, beeswax or paraffin, and
covering them over with two thicknesses of muslin.
The rubbing of the hot iron over this cloth absorbs just enough of
the wax to make the iron work smoothly. When the supply of wax is
exhausted, it can be easily renewed.

as the side of a bookcase, door facing or door panel, and strike
it hard with a downward sliding motion, pressing it against the
wood. Take the hand away and the coin will remain on the woodwork.
The striking and pressure expel the air between the quarter and
the wood, thus forming a vacuum sufficient to hold the coin.
