Looks workable Kev, maybe drop them a bit lower on the chest as well. As the plaid pin is only secured by the pin the edge of the medal ribbon could sit under it slightly. Is it a case of the old saying "here's your medal now go get a chest to pin ot on".
Cheers Simon
Cheers for the idea ...going to lower them so they sit half way between the top two buttons
Stay tuned
