Hi Carl,
I got a template for the side pockets from Loose Goose Down Supply in the US, he was very happy to email it. He has a youtube channel with instructions and you will find his email address there. The rest I sketched up myself. There are a few templates available on the net, but none of them really worked for me. So I adapted them to suit what I wanted so as to incorporate the design elements I wanted from various packs I’ve seen on the net.
