You can finish an edge in many ways. With bias binding, facings, narrow hem and  like this method I am going to show you here: A piped edge

You can make your own piping. However, I find the piping you can buy in fabric stores very good, so I buy it if I can find a matching color.

You can use  piping  as a design detail and sew it into a shoulder seam as I have done on the dress you can see in the picture. You can see how I have made the neckline here.

  • Place the piping edge on the right side of the fabric.
  • With a zipper food, sew as close to the piping edge as you can get. NB! A piping edge is cut on bias, so you can shape it over curves and edges with shapes.

 

  • Overlock the raw edge, all layers together.
  • Turn the seam allowance to the wrong side of the fabric and press from the right side
  • Using a zipper foot topstitch from the right side 0.2 cm from the piping
  • Now you have a piped edge. This is an ease and pretty way to finish an edge.
