Marking Ruler Trio

Use these rulers to quickly and accurately perform a variety of marking tasks. The center line is exactly 1/4 inch from both edges of the ruler. This provides an accurate reference line for: marking 1/4 inch sewing lines - adding 1/4 inch seam allowances - checking 1/4 inch seam allowances - marking 1/4 inch quilting lines. The three ruler lengths accomodate a variety of different size marking tasks. Use a pencil with a fine - sharp point for the most accurate mark. CAUTION: Do not use rulers with rotary cutters - knives or other cutting instruments. Rulers are designed for marking use only. Injury may result if rulers are used for cutting and trimming tasks.
