Perforated paper is a type of paper that has small holes punched into it, typically at regular intervals. It is used in hand embroidery as a guide for stitching, with the holes marking the pattern or design to be followed. The holes allow the embroiderer to easily see the design and keep their stitches in the correct place, while the paper itself acts as a stabilizer to keep the fabric from stretching or distorting while the embroidery is being done. Once the embroidery is complete, the paper can be carefully torn away, leaving the finished work behind.
