This is a flexible version of the standard vary form garment ruler design. It can be easily customised to create a ruler for specific proportions that are not catered to by generic pattern drafting equipment. The engraving can be filled in to make the markings more visible: dark for working with predomintantly light-coloured fabrics or light for the dark coloured fabrics. Custom rulers are great in a shared workroom: engrave your name into the plastic and never lose your ruler again!
Two designs can fit on a P3.
