All base and stringer moldings should be worked out of solid wood. Work that is to be bent is generally stronger when laminated, as shown in Fig. 16; but for moldings this method cannot always be used, since the joints will show, no matter how well the work is done. This is particularly true of hard woods. If the work is to be painted, however, this method is not objectionable.
