You're very welcome I'm sure! What did you use to go around the ends of the concertina to attach the harness to? Pictures would be good, perhaps we can come up with the perfect design by committee!
A bit Heath Robinson ish - a couple of those wire circles that are used for keyrings, attached to one side to neck strap attachments on the concertina, the other side attached to the harness. I've also added bits from the harness to the hand strap to turn the 'tina round a bit so the angle of the buttons is in line with my fingers when my hands / arms are straight. Not perfect but an awful lot better than a neck strap alone, or a single diagonal across the back strap. It means that I can practise while I'm 'running' on my cross trainer and convince myself that I'm getting my daily 30 minutes' exercise to give me a longer life to learn more tunes....
