Mandarin collars are a type of collar that is commonly seen on Chinese clothing. This collar stands up against the sides of the neck and comes together in a curved "V" shape at the front of the neck. This type of collar is similar to banded collars and is attached to the neck of the garment with a sewing technique called a sandwich. This type of collar can have a curved or flat top for the comfort of the wearer.
Measure around the neck of your garment. Add 1/2 inch to this measurement. This will be the length of your collar.
Lay a piece of fabric on a flat surface in front of you. Measure and mark two rectangles that are the same length as the measurement from Step 1. The width of the rectangles should be 4 1/2 inches wide.
Cut out both rectangles. Lay the rectangles on top of each other lengthwise so that the patterns face out.
Fold the two rectangles in half vertically. Cut the top corner into a rounded shape. Unfold the two rectangles. They should still be on top of each other with the patterns facing out.
Pin the two pieces together along the horizontal centre.
Fold the top, bottom and sides of the rectangle in the back down and in between the sandwiched rectangles 1/4 inch. Crease well. Fold the top, bottom and sides of the front rectangle down and in between the sandwiched rectangles 1/4 inch.
Remove the pins from the horizontal centre and reposition them 1/8 inch from the edge along the top and sides of the rectangle to secure the edges together.
Thread the sewing machine or sewing needle. Sew the top and sides of the rectangles together as close to the edge as possible maintaining an equal distance between your seam and the edge of the material. Remove the sewing pins.
Lay your garment on a flat surface. Identify the middle of the back of the neckline. Identify the middle of the collar along the bottom edge. Align these two centre points and slide the neckline between the front and back piece of the collar fabric 1/4 inch.
Insert sewing pins 1/8 inch from the edge along the bottom of the collar to secure the collar to the neckline.
Sew the collar to the neckline as close to the bottom edge of the collar as possible while maintaining an equal distance between your seam and the edge of the material.
The width of the collar can be adjusted shorter or taller for the desired appearance. The fabric used for the collar should be the same as the fabric used for the garment. Make sure that the patterns face the same direction before cutting out the fabric pieces for the collar.
