First, choose the right position to lock buttonholes and sew buttons, and start cutting the front and back of the vest. The front and back of the vest are made of different fabrics, and the same kind can also be used. Cut two front pieces and two back pieces. Note that if the fabric is thin and not stiff, it is best to add lining. Secondly, cut the fake pocket of the vest, the size is 2.5 cm wide and the hem is 1 cm. The length is up to you, not too long. Fold the three sides of the cut fake pocket inward 1 cm, and sew the unstitched side of the fake pocket opposite to the front of the vest.
Then turn up the fake pocket and fix the other three sides with hidden stitches. Find a piece of cloth with the right color and cut two pieces in the front. The lining and the front of the vest, do not sew shoulders and pleats, sew other parts. Finally, turn the front back from the rib, sew a string of lines, that is, open lines, and pay attention to the coordination of the colors of the lines. The back panel is opposite to the front of the lining, except for the shoulders and pleats. It would be nice to have such a beautiful children's handmade suit vest, and the production method is relatively simple.
