no response from Dan or Renee so maybe they're not biting? C'mon, everone loves "schwag" and you could have bunches in time for blade?
First idea to come to mind:
Dark red background with black and gray dawg head
for the subdued if there was enough interest:
tan/olive background with black and gray dawg head
ordered some Gadsden flags a few years back and I recall they come out to 2-3$ per but that is exponentially dependent on the number you order.
Like the tan and olive, think patches would be a good idea
