Step-by-Step Instructions:
Bound seams are a high-end sewing technique that encloses raw seam edges with bias tape or binding, creating a clean, durable, and attractive finish on the inside of garments and unlined projects.
Materials Needed:
- Fabric for your main project
- Double-fold bias tape or handmade bias binding
- Pins or fabric clips
- Scissors or rotary cutter
- Sewing machine
- Thread matching both your fabric and binding
- Iron and ironing board
Tips Before You Begin:
- Choose lightweight to medium-weight bias tape for curved seams and heavy-duty tape for thick fabrics.
- Pre-wash your bias tape and fabric to avoid shrinkage.
- Use a zipper foot if you’re sewing very close to the binding edge.
- Press your seam allowances open before binding for a crisp, flat finish.
1. Prepare Your Seams
- Sew your seam as instructed in your pattern using the desired seam allowance (commonly ⅝”).
- Press the seam open using an iron for a flat, even base to apply the binding.
2. Cut or Select Bias Tape
- Use store-bought double-fold bias tape or create your own by cutting fabric strips on the bias at a 45° angle.
- Cut strips 1½” to 2″ wide for most medium-weight fabrics.
3. Encase the Seam Allowance
- Open one fold of the bias tape and align the raw edge of the tape with the raw edge of the seam allowance, right sides together.
- Pin or clip in place along one side of the seam allowance.
4. Stitch the Binding to the Seam
- Stitch in the first fold of the bias tape (approximately ¼” from the edge), being careful to keep your seam allowance flat.
- Trim excess seam allowance if needed to reduce bulk before wrapping.
5. Wrap and Press
- Fold the bias tape over the raw edge, encasing it completely.
- Tuck the folded edge under and press in place so it overlaps the stitching line by a hair.
6. Topstitch the Binding
- From the right side of the bias tape, stitch close to the folded edge to secure the binding.
- Repeat for the second seam allowance if binding both sides individually.
7. Press and Finish
- Give the seam a final press for a crisp, polished look.
- Your bound seam is now neatly enclosed, durable, and visually appealing from the inside.
