Abstract
Multi-sided decorative moldings and furniture parts are manufactured by drying or hot-pressing a cellulosic fiber-containing mat to consolidate said mat into a unitary blank, cutting the blank to a size larger than interior dimensions of a closed mold in each of its three dimensions and with at least two generally shaped or profiled edge surfaces disposed between a top surface and a bottom surface of the blank. The cut blank is then molded at a temperature of at least 200.degree. F. for a period of time sufficient to permanently transfer the interior shape and design of the mold cavity to every surface of the blank.
