Some people wanted a clearer explaination of the use of bias binding for the curve of the Jacket
First picture shows what bias binding is.(crude drawing)

Line up the bias binding to the chalk line ( corner of one side to the chalk) & stitch to the outside of the jacket following the curve of the chalk line.

Other view

Finished view

Next trim off excess material (leaving 1/4")

Finished trim

Turn jacket over & fold the bias binding over(this now becomes the hem)

Sew the other end of the binding to the inside of the jacket using a cross over stitch as shown( we have used a white thread for demo purposes) you would use a thread to match the jacket

You then have to trin & sew back the lining to cover the bias binding etc.

The finished curve, take care while sewing the binding to the inside of the jacket to ensure you get a smooth curve

Hope this makes sense & is useful to some of you as you can save a lot of money by converting your own jackets
