Nice Work Alan H!!!

You have really put the effort into this thread to help people that may be looking to alter a jacket. The pics, diagrams, and text were great and I am sure will be a great help to everyone wanting to do this project.

About the only thing I can add, is have a bunch of pictures of the jacket you want, before you start cutting. If you want an argyle, find a bunch of different photos on line and print them off as a reference. It helps to know what you want the final project to look like.

The centre back vent may be an issue, but if you just want a casual jacket to go with a kilt, I am sure you can work around the centre vent issue.
