1. First put the white quilt cover (all made of pure cotton cloth) on the bed surface, and then put the cotton tires on it, so that the distance around the white quilt cover is as consistent as possible (even if the difference is big, it is not bad).

2. Spread the colored satin flat on the cotton quilt, then evenly stack the extra white quilt around it, completely cover the four sides of the red satin, and fold the corners of the wide head on the upper and lower sides into a triangle.

3. Prepare special tools for sewing quilts: cotton thread, large needle and thimble. Use a thread to thread the big needle obliquely from the top of the quilt to the bottom, leaving a proper distance (1.5~2 inches long), and then thread it back from bottom to top. Squeeze the front slightly with your thumb, and then push the small hole of the needle to the end with your middle finger. After the top, I pulled it again and all the needles and threads came out.

4. With the above method, one side of the quilt head is stitched and knotted from right to left to form a uniform straight line. In the same way, sew the other side of the quilt's long head, both of which are uniform straight lines. Get up and turn the quilt over to reveal the wide-headed side, fold it into a small triangle and cover it completely on the red silk. Start from the right corner of the quilt width, sew to the left to the other corner of the wide head, and then tie the needle and tie the knot.
