• To make continuous bias, start with a rectangle of fabric. Tear or pull threads to ensure all edges are on grain. Using a ruler with a true 45° line, mark a bias line beginning at one fabric corner.
  
  
• Determine the desired bias strip width. On the fabric wrong side, mark bias lines parallel to the first line and the desired width apart. Mark a 1/4" stitching line at the rectangle top and bottom.
  
  
• Mark points A and B as illustrated. Trim off the ends along the first and last bias line (Figure 1).

• With right sides together, match points A and B, and pin. Pin the remaining edges together, matching each set of bias lines at the stitching lines. The tube will appear somewhat twisted (Figure 2).
  
  Figure 2
  Match points A and B. Match bias lines along stitching lines.
  
  
  
• Stitch along the marked stitching line with 20 stitches per inch. Press the seam open.
  
  
• To form one strip of continuous bias, cut along the marked lines beginning at point AB and continuing around the tube (Figure 3).
