bit of merch advice....
hats should be at the very top of the list. if you think about it, most people have a closet full of t-shirts and jackets they rotate through, but usually only wear 1 or 2 hats. = maximum visibility
photo op is maximum, a persons head/hat is always in a photo, cant say the same for t-shirts....
any time ive done an event/tradeshow, i sell hats at a very discounted rate, and/or give some away as promo. win/win, as they always put them right on and wear them all day, makes for good brand recognition / brand presence.
patches are the best all-round medium, as you can put em on everything (including hats and beanies), and they should definately have a knife worked into the logo somehow.
so, PATCHES and HATS por favor senor cabesa de papas
