Episcopic projection system for making dress patterns - uses hip and bust measurements separately for accurate sizing

摘要

The patterns can be drawn to any size by episcopic projection. In the first step the part of the reduced pattern above the waist is brought to the original size with the bust measurement as the reference size whilst in a subsequent step the part of the reduced pattern beneath the waist is brought to the original size with the hip measurement as the reference. In this way by using the two measurements independently an accurately sized pattern can be produced even where the two measurements are not in the standard proportion. A tape measure on which the measurements for the hips and bust are placed separately side by side can be used to measure the distance between the projection appts. and the drawing support.
