The dressmaker's ruler offers a cornucopia of functions for producing patterns and markings on fabrics used by hobby or professional dressmakers in the work space. Measurements, such as seam allowances, button-holes and pleats, which are needed again and again, can be marked as easily as child's-play with this multi-functional ruler. Armhole and sleeve head, waist-lines, collars and hip-lines - none of these are any problem with the dressmaker's ruler from Prym. Its convex outer edge makes it possible to link marked single dots harmoniously after one trying-on. On the straight outer edges of the transparent plastic ruler there are 60 cm and 24 cm scales, marked to be easy to read. Button-hole sizes can also be determined and immediately marked with perfect accuracy.
