How to Cut Bias Binding: 9 Steps

Bias binding is a versatile and professional-looking finishing technique for the edges of your sewing projects. Cutting your own bias binding gives you the freedom to choose your desired fabric and width, ensuring that it perfectly matches your project. Here are nine easy steps to guide you through cutting bias binding.
1. Select your fabric: Choose a fabric that complements your sewing project and is suitable for making bias tape. Lightweight fabrics are often recommended, as they are easier to work with when folding and pressing.
2. Prewash and iron the fabric: Washing and ironing your fabric beforehand helps eliminate any potential shrinkage issues and makes for more accurate measuring.
3. Calculate desired width: Determine the finished width of the bias tape you want, then multiply this by two to account for both folded edges. Add another 1/4 inch (0.6 cm) for seam allowance.
4. Square up the fabric: Lay out the fabric on a flat surface with the selvage edge running horizontally. Fold the bottom edge up at a 45-degree angle to create a diagonal fold, aligning with the selvage edge.
5. Trim off excess material: Using a rotary cutter or scissors, trim away any excess material along the top edge of your folded fabric.
6. Mark cutting strips: With a ruler and chalk or a marking pen, measure and mark even intervals across the folded, angled edge of your fabric according to your desired width calculated in step 3.
7. Cut bias strips: Use a rotary cutter or sharp scissors to carefully cut along each marked line from one end of the fabric to the other.
8. Joining the strips: Place two strips right sides together at right angles, ensuring that their short edges align perfectly. Sew along their diagonal seam using a 1/4 inch (0.6 cm) seam allowance, connecting them into one long strip. Repeat this process with remaining strips.
9. Press seams: Trim off any excess seam allowance and press the seams open to ensure a flat finish, ready for use in your sewing project.
Now that you have successfully cut your bias binding, you can attach it to your project to add a clean, professional finish to your sewn edges. Whether you’re creating clothing, home décor, or quilting projects, cutting bias binding is a valuable skill that every sewist should master.
