Red line Magnifying Ruler, 8"
This ruler combines the practicality of a ruler and magnifying lens. Lay the ruler directly on top of your pattern or yarn swatch to double the image size; the optical quality lens is specially shaped to gather and direct ambient light to the viewing area. The inch and metric scales are set above and below the magnified viewing zone, for easy measuring. The red line helps you follow along the correct row in a chart.
