Bias piecing is the joining of two diagonal edges of cloth.


No. 8 needle, No. 60 thread, pins, scissors, and a piece of calico five inches square, cut by a thread.

Fig. 80.

1. Fold the square diagonally, from corner to corner.

2. Crease the fold, and cut on the crease.

3. From each piece of calico, cut two bias strips, each being one inch wide.

4. With the right sides upwards, place the strips on the desk in a line for joining, as in Fig. 80.

5. Place the right sides of the two middle pieces together, with the edges of the ends that are to meet even.

6 Move the edge of the upper piece, one-fourth of an inch to the left (Fig. 81).

7. Holding the edges securely, insert the needle at a (Fig. 81) and sew across to b (Fig. 81), with a running and a backstitch.

8. Press open the seam, and cut off the corners that protrude.

9. Join the other two pieces in a similar manner, except that the upper edge must be moved to the right.


To join the ends evenly, the seam must be begun at the vertex of one of the angles, formed at the side by the two pieces of cloth, and finished at the other. When many bias strips are required, they can be easily and accurately cut, by measuring for four widths, and then cutting into halves and quarters.

What is bias piecing? Where should you begin so as to join the ends evenly? Where finish?
