Rotary Cutting Bias StripsLong bias strips are used to make quilt binding and for applique shapes that bend easily into graceful curves--such as flower stems.
To cut long bias strips, align the 45-degree mark on your long rotary ruler with the fold in the bottom of the fabric. Hold the ruler in place and cut along its right edge.
You can cut bias strips along any 45-degree angle of the grain. For long strips, make your first cut near the upper left corner of the folded fabric.
To make the next cut, align the correct line on your ruler with the angled edge of the fabric and the 45-degree line with the fold. Rotary cut along the right side of the ruler again. Continue until you have the number of strips required for your pattern.
