How do enter a miniature class item in 2014 show?
This is the place you start. If you prefer to have a printed copy of the guide or if you have additional questions, please send an email to firstname.lastname@example.org. Note in the guide that information on the miniature settings is on p. 24 and that the chairs of that class are named and have contact information. They are there to answer your questions.
Hope this helps and thanks for your interest!
