Steps of making continuous bias tape
1. Cut a rectangle of a fabric – remember to maintain the straight grain. Cut off selvages if you use the full width of the fabric.
2. Mark a seam allowance on one of the short edges – 1 cm / 0.4 inch in my case.
3. Fold the rectangle so that the drawn line aligns with the bottom edge.
4. Cut the formed triangle off (along the fold line), and sew it to the opposite side. Press open seam allowances.
5. Draw lines parallel to the slanted side in a distance 2x desired width of bias tape. Mark the seam allowances (1 cm / 0.4 in) along the straight edges of the piece.
6. Join straight edges by joining opposite points on the lines intersections – offset by 1 point (as shown in the picture). It’s best to pin all the points to make sure that nothing moves during the sewing. It might look wrong and strange but after pinning all the points you will be able to lay the tube flat.
7. Sew it and check if the lines merge into each other on the joins. Press the seam allowances open.
8. Cut the tube all the way around along the drawn lines.
9. Press the edges, creating the bias tape.
