Abstract: A drapery length marking device having a ceiling bar and a drapery length indicator each of which is disposed generally horizontally and can be moved up and down to desired positions by crank means. The ceiling bar has a series of extending pins to enable quick and accurate securement of a drapery whose hem is to be marked. The drapery length indicator is precisely positioned by operation of knobs and can be inclined, if necessary, where an inclined hem is to be made. The drapery length indicator possesses a marking ledge so that an ultraviolet pencil or other marking tool can be pressed upon the drapery against the marking ledge to make a precise line corresponding to the location of the hem. The drapery length indicator also possesses an inner marking ledge so that the hem on the lining of the drapery can be marked. The invention is preferably operated by a cranking system to lessen cost.
