Hi Lynn,
apply to your breed club(s) requesting that your name be added to their list(s) which
should be updated and sent annually to all societies scheduling your breed ;) In the meantime, if you lack confidence being centre stage in the ring, why not ask to second steward at a few open shows and maybe your breed club show? It may help prevent self-consciousness (if that's an issue).
Since you will almost certainly have developed a good eye for your breed over the years through successfully exhibiting and breeding, have studied the breed standard and have made the effort to attend several seminars, you MUST know a fair bit by now and therefore others within your breed would be happy to pay for your formal opinion ;)
All that aside, even although judging appointments can cause the odd butterfly in the tummy the night before, you'll find all nerves/apprehension etc forgotten when you step into the ring and focus on the job in hand :)
Good luck, Teri
