The Olfa quilt ruler is ideal if you work a lot with quilts or other fabrics. Simply cut straight lines or choose an angle of your choice, the inch lines on the ruler will help you with this. There is a so-called 'frost' layer over the ruler, which ensures that the lines are clearly visible on light or dark surfaces. This is also a non-slip layer, so that the ruler does not slide. The size of this ruler is 15cm x 30.5cm.
