If you're binding around curved edges, you'll want to cut your binding strips on the bias. Here are two ways to cut bias binding strips.


Cutting and Sewing Bias Binding Strips

1. Begin with a fabric square or rectangle. Use a large acrylic ruler to square up the edge of the fabric and find the 45-degree angle.

2. Cut enough strips to total the length needed, handling the edges carefully to avoid stretching or distorting the strips.

3. Position and pin the strips perpendicular to one another with the raw edges aligned and right sides together. Mark, then join the strips with diagonal seams to make one continuous binding strip. Trim the excess fabric, leaving 1/4 " seam allowances.

4. Press the seams open and trim the dog-ears

Making Continuous Bias Binding from a Square

Rather than cutting individual bias strips, you can cut and seam a square to make a continuous bias strip.

1. Cut a square from your binding fabric on the straight grain. Click here to download a chart of the amount of continuous binding you can cut from various size squares.

2. Cut the square in half diagonally to form two triangles.

3. With right sides together, align two short triangle edges. Sew the triangles together with a 1/4" seam allowance to make a parallelogram. Press the seam allowances open.

4. Use a quilt marker or pencil and a ruler to draw lines parallel to the long bias edges, spacing the lines the desired width of the binding strip. (For example, space the lines 2" apart for a 2"-wide binding strip.)

5. With right sides together, bring the straight-grain edges together and align the raw edges to create a tube. Offset the edges by shifting one down so that the top of one edge aligns with the first marked line of the opposite edge.

6. Holding the fabric in this position, sew the bias edges together with a 1/4" seam allowance. Press the seam allowances open.

7. Begin cutting on the top marked line and cut in a continuous spiral. Each time you cut across the seam, you'll be moving down one marked line.

Quick-Cut Bias Binding

To quickly cut binding strips on the bias, start with a fabric square or rectangle. The diagrams shown illustrate a 5⁄8-yard length of 42"-wide fabric. If your fabric piece is a different size, the folded fabric may look different, although the instructions will be the same.

1. Lay out the fabric so the selvage edges are in the upper right and lower left. Fold the lower selvage edge to the cut edge, creating a 45º angle.

2. Fold the bottom corner up on top of first fold.

3. Fold top corner down on top of first and second folds.

4. Using a rotary cutter and acrylic ruler, trim off left-hand folded edge.

5. Cutting from trimmed edge, cut the desired-width bias strips.

6. Strips will be a variety of lengths; piece strips to equal the desired length of binding strip.
