Abstract
Abstract A ferrous metal weight and a magnetic plate are placed on opposite sides of a thin sheet of paper, forming a pattern. They are juxtaposed so that they are attracted to one another and grip the pattern. When laid out upon a cloth, the weight and plate position the pattern with respect to the cloth to be cut. A plurality of such weights and plates are used to hold the pattern in position.

Claim 1
Independent Claim
167 words
A method of precisely adjusting thin paper sheet pattern pieces on substantially planar textile material, comprising the steps of: placing a plurality of distinct magnetic objects on one side of each of the pattern pieces to be adjusted; placing a like number of magnetically attractable objects on the other side of said pattern pieces; juxtaposing said magnetic objects and said magnetically attractable objects so that they are magnetically attracted and grip the pattern pieces therebetween, said magnetically attractable objects having gripping means thereon spaced remotely from the surface to be used to engage said pattern pieces; utilizing said gripping means to exert divergent forces within the planes of each pattern piece thereby causing each pattern piece to assume a fully extended substantially flat position while moving, rearranging, and exactly repositioning the pattern pieces to their desired location on the material, and then releasing said pattern pieces thereby allowing the weight of said magnetic objects and magnetically attractable objects to retain said pattern pieces in a precise location.
