Abstract: A dart depth gauge comprises two flat members pivotally connected with one another. The two members have index points which are spaced from the pivot and are movable toward and away from one another by relative pivotal movement of the members. One of the members has along one edge a scale which is calibrated in terms of pattern sizes. The other member has thereon a series of curves, each of which is identified by a breast cup size. The curves are laid out so that when the members are pivoted relative to one another to bring the calibration of a selected pattern size into coincidence with a selected cup size curve, the distance between the index points is the correct depth of dart for the selected pattern size and selected cup size.

Abstract: An implement for coordinating the colors of fabric and the like comprises a circular base portion of cardboard or other stable sheet material having therein a series of circular openings which are arranged in a circle concentric with the base member. Each of the openings is surrounded by an annular band of color, the colors of the band being selected in such manner that colors which blend are disposed adjacent one another while contrasting colors are located at the opposite side of the base member. Each of the annular color bands is divided into a plurality of sectors which are shades of the respective color. A central indicator member is rotatably mounted on the base concentric therewith and is of smaller diameter than the base member so as to be located inside the circle of openings and their respective color bands. The indicator member bears indices indicating the key color, adjacent blending colors and opposite contrasting colors.
