Guide Review - Omnigrid Marking Ruler Trio
You can mark and measure small patches with rotary rulers, but their larger sizes sure make them awkward to handle. Omnigrid's solution, a set of three narrow marking rulers, each one exactly 1/2-inch wide.
The set includes a four, six and twelve inch ruler, all with 1/8-inch markings down their sides and a narrow rule running straight through their centers that's exactly 1/4-inch from outer edges of the ruler. It's the 1/4-inch mark that you'll use most often.
Using the Marking Rulers
- Align a ruler's center line along the edge of a drawn, uncut patch and mark along the edge of the ruler to produce an exact 1/4-inch seam allowance. Cut out on the line.
- Reverse that process and place a ruler's straight center line on the edge of a cut patch that includes a seam allowance. Mark along the inward edge to define the seam. This would be helpful for set-in patches and hand piecing.
- Align the center rule with two opposite corners of squares used to make quick half-square triangle units. Draw lines on both sides of the ruler to represent your sewing lines.
- Use the rulers to mark quilting lines.
For best accuracy, be sure to use a fine-point marker--the finer the better.
