This amazing multi-tool moves smoothly in increments you set, making it easy to create calligraphy guidelines, draw shapes such as circles and squares, mark parallel lines, and more.
Tips for use: Draw your first guideline. Then make a single column of dots or small marks for each subsequent line. Line the rolling ruler or parallel guide on the first mark. Then you roll down and draw your guidelines at your marks. The ruler keeps the lines parallel. Mark your paper using a ruler, template or dividers with tick marks. Great for drawing guidelines for text blocks on larger works where a T-square is not practical.
