Chris, just an option for you....
here are a few pictures of a flag that Pamela did for me a few years back for my Arkansas Traveler, i.e. "Flagchick" that MarkS mentioned, her email address is theflagchick@hotmail.com, she advertises on eBay.
The quality is fantastic. She embroidered both sides (reversed), very professionally done, double sided flags with Tyvec, which is a light blocker so the opposite side won't show through, with a sewn border. This flag she did for me was very custom... I scanned in pictures of an old boat brochure showing the Arkansas Traveler logo, custom picked the colors for my boat application, and she also reduced the size to fit my flag pole (10" x 15"), as opposed to the advertised 12" x 18", as many of the older boat flags were smaller in size than newer ones. For some applications, you can also let her know if it needs to be raked, (if the pole rides on a 30 degree (r so)angle then the flag should probably be raked). Anyways, bottom line is that she makes a lot of these and can custom make it to whatever your specifications are. I paid $45. Also, she was able to make it and send in just a few weeks. May be worth checking into/just an option. The "double sided" option is nice.
BTW... I like the original Red w/White script Glastron name.
Thanks Chris!
