1. Subtract 3cm edges from both sides of the front and back pieces of the pattern, and cut them into 6cm strips with double threads, with one layer of double threads and two layers of non-pile.

2. For each cut piece, there are 4 lining pieces, 2 surface cloths and 2 interlining pieces. After cutting 3 cm off each side, replace it with elastic cloth strips, each side is 3 cm, two pieces are 6 cm, and the seam width is 8 cm.

3. Put the tablecloth, two pieces of interlining and the car together in a circle, leaving a cashmere filling opening of about 7 cm at the trouser mouth.

4. Fill the down, seal it, spread it out, pat it evenly with a ruler, and then draw a horizontal line. When making a horizontal line, the tablecloth is on it, and I press my foot with a plastic presser. I press the front of the car with my left hand and hold the cloth without a car in my right hand to prevent the tablecloth from eating too much ground cloth.
