"The smoothing board, or mangle board, has its roots in Scandinavia and Europe. The smoothing board has two components - the flat board with handle and the roller stick which is about 2 to 3 inches in diameter. Tp use the smoothing board, the dampened fabric is folded in panels and wrapped (rolled) tightly around the roller. Using a flat surface like a table, the smoothing board is then pressed (at right angles) down on the rolled fabric and wood roller stick. By applying pressure in a rolling manner, the fabric is pressed and then removed from the roller." David Irons, More Irons By Irons, page 17.
