Instructions
Cut the collar off the shirt just below the neckband.
Iron the collar flat if needed.
Cut the upper part of the collar (the decorative part) from the lower part of the collar (the neckband that attaches it to the shirt) along the seam.
Lay the upper part of the collar on a large piece of paper or the right side of a piece of fabric.
Measure 5/8 inch from the edge of the collar to mark the cutting line for the collar pattern. Use a pencil to mark this distance on the paper, or use a pin to mark it on the fabric.
Repeat step 5 all the way around the collar, so that the pencil or pin markings for the collar pattern are 5/8 inch larger than the old collar all the way around.
Cut out the paper pattern or fabric.
Repeat steps 4 through 7 for the neckband (or lower part of the collar).
